Daniel, if you wish to learn from your mistakes them you must listen. Peter is
not someone whose input you should dismiss. The function you have showed us
never worked as you have described it. However, if you give .GlobalEnv as the
first argument in the call to ls() then it should work.
You wi
Thanks! I was not aware of the browser() function, seems pretty useful for
debugging.
However, for this particular case, adding it to the mentioned function doesn't
do much: Again I get no errors, no output in the terminal and no files are
created.
If I include browser() within the for-loop (no
Maybe a daft question arising from lack of reproducible example, but have you
run ls() manually to make sure there are objects that _exactly_ match "_Figs_" ?
The simplest explanation for a loop doing nothing is that there are no cases.

I discourage the use of print() for debugging.
Put a browser() statement into your loop and when execution takes you to the
debugger interface, examine your variables and expressions one by one.

To your first comment: Yes, the function used to work, and the loop inside it
still does (as indicated in my first email). I wouldn't bother asking otherwise.
To your second, no, specifying the environment in the ls() call doesn't help,
the problem persist.

It probably helps if you tell ls() which environment to list, as in:
> f <- function() ls(.Global
Thanks, but printing doesn't work within the function either. (i.e, no
result or output, or error). Also, like I said, the loop is working
fine on its own (so the path, name, filename, and all other variables
called from the function exist, are available and are recognized just
fine). It just doesn
How about inserting print() statements on the output of "ls()" and the value of
"filename". In particular, is the value of Plots_path the same as last week?

The following function is supposed to search the workspace and save
plots (i.e. listing all objects in the workspace named "Figs", which
are all ggplot2 plots, and saving them as png files)
SaveFigs <- function()
{
for (i in ls(pattern="_Figs_"))
{
filename = paste
9 matches
