pad leading zeros in front of strings
Dear All,
This question sounds very simple but I don't know where I am wrong. I just want to pad leading zeros in some string, for example, "123" becomes "00123". What is wrong if I do following?
> sprintf("%05s", "123")
[1] " 123"
It didn't return "00123", instead it padded with 'blank'.
Thank you for your help

re-install a package
Hi All,
I have a self-cooked package and save it to a zip file after running make, say named xxx.zip. After installing it to R by running "Install packages from local zip files" under Packages menu in R (Windows), I realized I needed to change some source codes and re-make it. My question is that if I need re-install that package or R would automatically update the R

Scrollable DIV causes flicker in FF - SlideDown & SlideUp
I have a fixed height scrollable div inside another
div that controls the slideDown and slideUp effects.
This causes a really bad flicker in Firefox (1.0.7)
for the entire duration of the slide down and up.
While on the other hand it works smoothly in IE
(except that on a slideUp it causes a last second
flash that shows the entire div).
Any ideas on how I can fix this?
Thanks.

possible scriptaculous bug
I have two sortable lists, one after the other. I can drag from the first
to the second but not from the second to the first. The behavior is
consistent if n > 2. For example, I can drag from 1 to 2, 3 or 4 from 2 to
3 or 4 and from 3 to 4, but not in the reverse order: I can''t drag from the
4th list to anything (besides itself). From the third list I can drag only
to itself and 4.
