When calling a script, I want to print the code expressions and their
results using echo=T as in:
> source("myscript.r", echo = T)
This seems to do pretty much same as print() if the script only lists
expressions like "mean(data)", and echo seems nicer since it avoids extra
print statements.
But when I use the same expressions inside a for loop (to process multiple
files), only code expressions and no results are echoed back.
My questions:
Does "echo=T" not print results of functions in loops?
What the major difference between echo and print?
Thanks!
