If its too large the the primary portion of the objective basically

You could create an S3 generic that does it. That is not initially
any less work than the if statement but if you add new distribution
no existing code need be modified. Just add a new method for each
distribution to be supported:

I'm trying to save the workspace as a Check Point for
possible future come back. The "save.image" function
works if the whole coding is in a main function:
rm(list=ls())
t = 1
t = t+1
print(paste("before",t))
# [1] "before 2"
save.image("tt.RData")
t = t+1
print(paste("after",t))
# [1]
save.image() saves the global workspace: it does not save the environments
of executing functions. If you want to save the latter, use the 'envir'
argument of save().

Thanks for your response. Here is an example I took from graphics gallery (
http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=2 ). Now I
want to place 4 plots into the same page (e.g., one for swiss, one for usa,
and so on) by running the author's function plotacpclust() 4 times.
I have a dataframe say:
date price_g price_s
0.340.56
0.360.76
. .
. .
. .
and so on. say, 1000 rows.
Is it possible to add two columns to this dataframe, by computing say
diff(log(price
Thanks a lot, it works!
Now I have to find out why - but I think I can/should do it on my own ;o)
