Thanks you very much.
The issue resolved by just upgrading the R and R studio to their latest versions. All the packages are now successfully installed. Henceforth, the code runs absolutely okay.

Hello,
Works with me, but I'm using R v 3.3.0. Note that your version of R is over 1 year old, try updating it.
install.packages("caret")
install.packages("e1071")
library(caret)
library(e1071)
set.seed(100)
tr.control <- trainControl(method="cv", number=10)
class(tr.control)
[1] "list"
Hope this helps,
Rui Barradas

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.

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
