r - Why does sourcing a script not print out to stdout? -

in r session, source simple r script content is:

x = c(1,2) x 

as

source('my.r') 

i wonder why running in r session doesn't show output?

(i find can use print() show value of x.)

thanks.

it way source configured. can change options echo , print.eval:

echo logical; if true, each expression printed after parsing, before evaluation.

print.eval logical; if true, result of eval(i) printed each expression i; defaults value of echo.

so try source("my.r", print.eval=true)
