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) } On Tue, 20 Feb 2024, 15:46 Bert Gunter, <bgunter.4...@gmail.com> wrote: > I believe you will have to expain what you want more fully, as what you > requested appears to be exactly what source() does, to me anyway.
