labels of a conditioning variable in xyplot
Error in do.call("pmax", lapply(cond, is.na)) :
symbol print-name too long
When I delete the labels vector, the code runs without difficulty.
Any thoughts on this error message?
Yes ... the labels are too long to be printed in the space available. Use shorter labels. For example, remove "Reference" or abbreviate it to "Ref" , as it provides no unique identifying info anyway.

Subject: [R] labels of a conditioning variable in xyplot
I am running R 2.1.1 on a Mac g5 under Mac OS 10.4.2.
I have an xyplot with a single conditioning variable (8 levels) .
Here is the code for the conditioning variable used in the formula
argument of xyplot:
factor(
drugauthoryear,
levels = c(
'bupicapogna1999',
'levobenhamou2003',
'ropicapogna1999',
'ropipolley1999',
'bupipolley1999',
'levopolley2003',
'ropibenhamou2003',
'ropipolley2003'
),
labels = c(
'Bupi. Reference 2.',
'Levo. Reference 4.',
'Ropi. Reference 2.',
'Ropi. Reference 3.',
'Bupi. Reference 3.',
'Levo. Reference 5.',
'Ropi. Reference 4.',
'Ropi. Reference 5.'
)
)
The object is not created and I get the following error message:
Error in do.call("pmax", lapply(cond, is.na)) :
symbol print-name too long
When I delete the labels vector, the code runs without difficulty.
Any thoughts on this error message?
Thanks,
Nathan
