could not find function "createDataPartition"

You have to load the library before using its functions, in this case, I think the library is caret so try running this first.

library(caret)

I Did it again now it's done , i Don't know why but it's working now .

You only have to install the package once but you need to load it on each new R session you want to use it on.
