[R] Including an external set of coded

[CALUM POLWART]

Are you asking to source lines 5-10 of a file for instance?

Never seen that done in R. Feels a dodgy thing to do as changing line will
screw things up.  On the other hand - I'd often have functions in a file
called perhaps "functions.R" and source("functions.R")

Then I can call an individual function something like

tranform_mydata(mydata)



With the functions.R containing

transform_mydata <- function (mydata) {

mydata<-transform(mydata,
a<-b+c
d<-e+f

return(mydata)
}
