Background:
Data from 289 Emory ICU patients was collected between March and June of 2020. All patients were COVID positive. We will focus on lab values.
Task:
You will create an commented R script that does the following:
Using pacman, load the tidyverse and rio packages
import the QCRC Data, specifically the Long_Labs sheet into a data frame called qcrc_labs
Create a new data frame called creat made by filtering filter the qcrc_labs data frame to only observation with a creatinine value over 1.5How many labs meet the criteria? (answer in your comments in your script)
Continuing with the same data (use a pipe) use the distinct function to count the number of unique patients in the creat datasetHow many patients do you get? (answer in your comments in your script)
Now, create a new data frame called hemo based off of qcrc_labs, lets understand how many patients have a hemoglobin value.Filter to non-missing hemoglobin labs remainWrite in the comments how many labs remain? (answer in your comments in your script)
Use the skimr package to answer the following:When using the qcrc_labs data frame:What is the mean and median hematocrit value?(answer in your comments in your script)
Using the hemo data frame:What is the mean and median hematocrit value?(answer in your comments in your script)
What is the difference in hematocrit before and after filtering?(answer in your comments in your scriptData:

Your R Script showing each step. It should be well commented.

Hi all the documents needed is in the zip folder please read the instructions pdf and write the asnwers on the rmd file attached, also keep in mind this instruction:
“Open the RMarkdown document with surfix
“.rmd” via RStudio. Click Knit to create a PDF document (remember to install the necessary packages
in your R). By removing the results=’hide’ and fig.keep=’none’ options in the code chunks, the code
outputs and the plots would display in the created file. For more information about the RStudio, refer to
the section Getting Started; about the RMarkdown, refer to the online tutorial and the online manual of
knitr by Yihui Xie from RStudio, Inc.
Please turn off the display of example code chunks (by specifying include=FALSE),
complete the exercise code chunks (remember to turn on the eval option), fill in
your name and create a PDF document, then print and submit it.”
This is in the instructions pdf but just pasting it here just in case.

write an code in R language that how we can import dataset and get details to show rows and columns.

Provide in the plain text R commands that finds/solves the following:
Create an integer variable e holding the value 42! Check the object class of e with class()!
Convert e to the character data type with as.character()! Check the object class again!
Create a character vector friends with four names from your circle of friends or acquaintances!
Index the second element from the vector friends!
Replace the first element of the vector friends with “Isolde” and check the updated vector again!
Create a vector v1 from the following elements 1, “Hello”, 2, “World” ! Check the object class!
Create a vector v2 with numerical values (only integers) ranging from 4 to 10!
Index the first three elements from v2!
Index all elements of v2 except the second element and save the result as v2.subset!
Use the length() function to find out the length of v2.subset (= the number of elements in the vector)!

These are a few questions for an assignment for a Statistical Models and Data Mining course. Please make sure to follow the instructions/guidelines provided to complete the questions! This is very important! I have attached the instructions for this assignment. It is an Rmd file. Please make sure to check that all the instructions are followed and that everything that is being asked for is completed in what you give me. Let me know if you have any questions or if there’s something that you find confusing about the instructions that you would like me to clear up with you!

Previous tutor canceled without notification, please only bid if you have reviewed the problems and are confident you can answer them.
Please see the attached instructions. Three files must be submitted, the R script for the functions, the R markdown file that generates the output, and a knitted html or PDF of that R markdown file. Ignore the line that states to only use notes; any solutions are fine.
