Greetings to all:
I am using S-plus v4.5 for Windows 95. I'll try to explain my doubt quickly:
I have 2 data frames (50000 x 150 & 3000 x 150) with the same number of
columns and same column labels. The data in these columns is of almost every
type. My "problem" is I get this warning message when I rbind them 3 times:
Warning in "[<- .factor" (.A0,ri,value = .A1): replacement values not
all in levels(x): NA's generated.
I have made sure that the data type are the same pair by pair, i.e. I do
not concatenate columns of different data type. My data frames have NA's in
much more than 3 columns so it is not a NA problem. ri (look warning
message) is not a variable name
Can anyone tell me what that means?. Is it a problem a should take care of
or is it just a bug because of the size of the data frames?. Thanks in
advance.
