Cannot find createDataPartition

Question

Good day everyone, I tried installing the caret package in R with the following codes but I am having an error stating that Stringi is not found despite trying to install that, I got a failed attempt.

Also, I tried to partition my data using the create createDataPartition function but I got the error "**could not find function createDataPartition

The codes I used:

install.packages("caret")

library(caret)

install.packages("stringi")

library(stringi)

The results are below:

**install.packages("caret")**
*Installing package into ‘C:/Users/Anuli/OneDrive - The University of Texas-Rio Grande Valley/Documents/R/win-library/4.1’

As a result of the stringi not found error, I am unable to split my data:

myData$cyl <- as.factor(myData$cyl)

sapply(myData, is.factor)
  mpg   cyl  disp    hp  drat    wt  qsec    vs    am  gear  carb 
FALSE  TRUE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE 

set.seed(1)

index <- createDataPartition(myData$cyl, p=0.75, list=FALSE)

Error in createDataPartition(myData$cyl, p = 0.75, list = FALSE) : 
  could not find function "createDataPartition"

You say you used the code `install.packages("caret")`, but you get a warning that "package ‘CARET’ is not available... Perhaps you meant ‘caret’ ?". Are you sure you used `install.packages("caret")` not `install.packages("CARET")`? R is case-sensitive. — Gregor Thomas, Mar 30 '22 at 17:03
Oooh, I'm also noticing that the messages say "Installing package into ‘C:/Users/Anuli/OneDrive ...". OneDrive often makes things weird for accessing packages. I'd strongly suggest [following the steps in this answer](https://stackoverflow.com/a/39056424/903061) to create your package library (the folder where R installs packages) on your local drive, not in OneDrive. — Gregor Thomas, Mar 30 '22 at 18:07
Thank you so much guys! @Gregor Thomas, I followed the steps as you suggested and I created the package library on my local drive as opposed to the OneDrive. — Anulika Azubike, Apr 05 '22 at 00:39
