Firstly, many thanks for kind consideration.
***I wrote the following R code:
install.packages("caret")
install.packages("e1071")
library(caret)
library(e1071)
set.seed(100)
tr.control <- trainControl(method="cv", number=10)
Error: could not find function "trainControl"
cp.grid <- expand.grid(.cp = (0:10)*0.001)
tr_m <- train(project_delay ~ project_lon + project_lat + project_duration +
sector + contract_type + capital_value, data = trainPFI, method="rpart",
trControl=tr.control, tuneGrid = cp.grid)
Error: could not find function "train"
I hope this will explain the situation I am facing right now.

Subject: Re: [R] trainControl and train functions are not found in caret package
Reproducible example? At least whatever you did... and the output of
sessionInfo().
Did you use library function to load it into memory?

Hi All,
Whilst using 'trainControl' and 'train' functions in R studio, an error is
raised stating that the functions are not found.
I tried installing the caret function a few times, but the error persists.
Can anyone guide me how to access these functions.
Many Thanks and
Kind Regards
