I have an already saved R script, say "analysis1.R". I use source("analysis1.R") command to run the R script when required in a different code.

How does one execute only the required lines of code? Say first 10 lines of the code ("analysis1.R")?

  • Here is a partial solution I found. Say from=1 and to=10 x = scan("analysis1.R", what = character(), sep = '\n', skip = from - 1, n = to - from + 1, encoding = 'UTF-8', quiet = TRUE) eval.parent(parse(text=x)) – Sesha Meka Apr 21 '19 at 15:26

from=1 
to=10
x = scan("analysis1.R", what = character(),
    sep = '\n', skip = from - 1, n = to - from + 1,
    encoding = 'UTF-8', quiet = TRUE) 
eval.parent(parse(text=x))
