- msleep**** For this assignment, you must name your R file msleep.R (using Rstudio) For all questions you should load tidyverse. You should not need to use any other libraries. Load tidyverse with suppressPackageStartupMessages(library(tidyverse)) The actual data set is called msleep Round all float/dbl values to two decimal places. If your rounding does not work the way you expect, convert the tibble to a dataframe by using as.data.frame() All statistics should be run with variables in the order I state E.g., “Run a regression predicting mileage from mpg, make, and type” would be: lm(mileage ~ mpg + make + type...) Before attempting to answer these, or if you lose points upon an attempt, please review all CodeGrade information provided in the CodeGrade overview submodule - if you do not you are likely to lose points. What is the variance in total sleep for carni vores and those whose conservation status is lc? Your answer should be in a 1 X 1 data frame with a value…This Phyton: In this lab, you will write a program that reads integers from a file “data.txt” into a list, print the list and the sum of the numbers in the list. The file contains one integer per line. You are not required to do any exception handling. Your program should not prompt the user for any input. The input file is “data.txt”. First, create a file “data.txt” and put the numbers add the numbers 3, 1, 5, 2 into it, one number per line as shown in the sample “data.txt” file below. Sample “data.txt” file 3 1 5 2 Then, write the following functions: read_numbers(filename) Read numbers from the given file and return a list of contains the numbers from the file. compute_sum(numbers) Compute the sum of the given the list numbers. Do not use the built-in sum function. main() Read numbers from the file “data.txt”, print the list, and compute the sum and print it. Main will use the two functions above to get the job done. Sample run: [3, 1, 5,…The file Scores.txt contains scores of your students. Write ONLY TWO VB.NET INSTRUCTIONS to clone the Scores.txt file to Scores1.txt in the same folder USING IO.FILE METHODS AND ARRAYS: Private Sub btnClone_Click(sender As Object, e As EventArgs) Handles btnClone.Click ………………………… ………………………… End Sub
- Select everything wrong with this code segment. int main(int argc, char* argv[]) { FILE* fPtr = fopen(argv[0], "w"); } O A. It erases the program it's running from, which may cause a crash. O B. argv[0] may not be a file. OC. If no parameters are passed on the command line, the program won't execute. O D. fPtr is a reserved word and can't be used as a variable. E. file names used by fopen must be quoted constant strings F. argv[0] is not guaranteed to existPart 1: Encryption A. Using your FileReader, read the file "PlentyOfRoomAtTheBottom.txt" in the Labs Module. There are non-printable characters in the file. Sometimes FileReaders abort when encountering a non-printable or extended ASCII characters. Handle this with exception handling if it happens. Your program should continue processing instead of aborting. Assign a specific character, of your choice, to the aborted character. B. Using the rawdata from reading the "PlentyOfRoomAtTheBottom.txt", develop a frequency counter algorithm for each character the lower ASCII table. For example: Character[ a ] = Frequency[ 2475 ] Character[ b ] = Frequency[ 420 ] Character[ c ] = Frequency[ 985 ] C. Sort the Lower ASCII frequency characters (i.e. 1 to 128) in decending order and process the data by using your QTree algorithm. Your QTree algorithm should be based on a PRIORITY_QUEUE. D. Create bit-trails, as defined in the Exercise Bit-Trail, for each character your QTree. E.…Try reading the contents of animals.txt and from there create a file named animals-sorted.txtthat is sorted alphabetically.The following code listing is the body of the animals.txt file.
- Install and load readr: library(readr). Then, import a text file with values separated by a single space: single_delimited.txt (see attached) tell R that missing values are represented with a period in the data we are importing (use the read_delim())You are given a text file (Words.txt) containing 50 words that will be hard to make out because they have been littered with punctuation. Your task is to: • Create a new file called Words2.txt, from Words.txt, which contains all the strings from the previous file, with their position, but with all the punctuation removed. (You must create some sort of method that can loop through the words to do this, you are not allowed to use Regex Patterns) Hint: This might come in handy String punctuation = "!\"#$%&'()*+,-./:;<=>?@[\\]^_`{|}~"; • You must find the first longest word that appears in the text file with their position retained as well as indicating the number of characters therein, the formatting for this can be seen in Table 1.Fix the spwd code so it works: /* spwd.c: a simplified version of pwd** starts in current directory and recursively* climbs up to root of filesystem, prints top part* then prints current part** uses readdir() to get info about each thing** bug: prints an empty string if run from "/"**/#include <stdio.h>#include <sys/types.h>#include <sys/stat.h>#include <dirent.h>ino_t get_inode(char *);void printpathto(ino_t);void inum_to_name(ino_t , char *, int );int main(){printpathto( get_inode( "." ) ); /* print path to here */putchar('\n'); /* then add newline */return 0;}void printpathto( ino_t this_inode )/** prints path leading down to an object with this inode* kindof recursive*/{ino_t my_inode ;char its_name[BUFSIZ];if ( get_inode("..") != this_inode ){chdir( ".." ); /* up one dir */inum_to_name(this_inode,its_name,BUFSIZ);/* get its name*/my_inode = get_inode( "." ); /* print head */printpathto( my_inode ); /* recursively */printf("/%s", its_name ); /* now print…
- pls code in pythonplagiarism: This Boolean function takes two filenames. If any line occurs in both files, return True.If not, return False. I suggest using nested loops. With nested loops, we call the loop that is in thebody of the other loop, the "inner loop". The loop that contains the inner loop is the "outer loop". Openthe second file inside the outer loop:for line1 in file1:file2 = open(fname2)for line2 in file2:Python only lets you read the file once per open, so you need this order of instructions. Make sure yourreturn False is outside of both loops. Otherwise, you will only compare the first two lines of thefiles. Make sure you close the file that gets read repeatedly after the inner loop but still inside the outerloop.Here is some (more complete) pseudocode to get you started:open file 1for line1 in file 1open file 2for line2 in file 2:if line1 == line2:return Trueclose file 2return FalseWrite a program that uses a sentinel loop (use ‘X’ as the sentinel value) and a dictionary that allows a user to input names and email addresses that are stored in a dictionary as key-value pairs. The program should then use a second sentinel loop to allow the user to look up a person’s email address until ‘X’ is entered. The program should pickle the dictionary and save it to a file when the user exits the program. Each time the program starts, it should retrieve the dictionary from the file and unpickle it. Please use Pythonwrite the code to lookup, add and remove phoneentries from the phonebook text file . These are the code we use for the lookup, add and remove in the case statement.(Lookup)# Look someone up in the phone bookgrep $1 phonebook (add)echo "$1 $2" >> phonebooksort -o phonebook phonebook (Remove)grep -v "$1" phonebook > /tmp/phonebookmv /tmp/phonebook phonebook Write a complete Bash script which will accept up to three command-line arguments: the first one is either (lookup, add or remove), the second one is a name enclosed in single quotes and the third one (if doing an add) is a phone number enclosed in single quotes. Using a case statement to match on either lookup, add or remove, the script should then perform the requested operation. Again here, you should first check for null arguments before continuing with the rest of the script or requested operation. In addition, the person may not be in the phonebook for lookup or remove so, you need to account for this.
