R help - May 2011 - reshape::cast: invalid 'yinds' argument

Hi,

I'm using reshape to cast molten data. When I use the following command, R 
either crashes (when I use Notepad++) or gives an error (when I use Rgui or 
source()), BUT the error occurs not always, maybe only on half the attempts:
w <- cast(v, id + code + productname + year + begin + end + specificDesc + 
specificDesc2 ~ type)
Error in merge.data.frame(data, all.combinations, by = unlist(vars), sort = 
FALSE,  : 

  invalid 'yinds' argument

What does this message mean, and how can I get rid of the error? I tried 
changing the colvars from character to factor, but that didn't help.

I'm using R2.10.1 and either WinXP or Win2000.

 Thanks in advance,
Albert-Jan

Hi Albert-Jan,

It's impossible to know what went wrong without a reproducible example
(https://github.com/hadley/devtools/wiki/Reproducibility).  Without
that, all I can recommend is trying out reshape2.
