Saptarshi,
how did you create those lists? Can you send us the code? If not, can
you put up the .RData file? Without a reproducible example this is
hard to debug ...
Thanks,
Simon

Hello,
I have list of 600K lists, each sublist a list of two elements, the
first a character, the second a list of six named elements, some
characters some numrics.
LISTA (600K) (:= h)
|__ List of two elements
|__ Character
|__ Named List of 6 elements (characters and numerics)
This works,
sip <- lapply(h,function(r) r[[2]][['sip']])
but I wish to unlist this
sip <- unlist(lapply(h,function(r) r[[2]][['sip']]))
and get the following error:
Value of SET_STRING_ELT() must be a 'CHARSXP' not a 'list'
Debugging to find which:
i<-1
sip <- unlist(lapply(h,function(r) {
i<<-i+1 #debug messages
cat(i,"------------------>","\n"); print( r[[2]] ) #debug message
r[[2]][['sip']]
}))
[1]Error in print.default(r[[2]]) : 'getEncChar' must be called on a
CHARSXP
Which occurs on the 122,204'th item. All entries r[[2]] are similar
so I don't know why this happening?
The strangest thing is that this error never happened a few days ago
and the same code causes this to occur today.
Any ideas would be helpful.
Regards
Saptarshi
