Hi,
I was trying like to print out data frame with POSIXct column
in html format using xtable package, but I got error message
when trying to print the table. Here is example:
aaa<-data.frame(as.POSIXct(strptime('03 2005', '%d %Y')),0)
aaa.tab<-xtable(aaa)
print(aaa.tab)
Error in Math.POSIXt(x + ifelse(x == 0, 1, 0)) :
abs not defined for POSIXt objects
I was able to get around the problem with converting column
back to string but still I would like to know is it a bug or
I was doing something wrong.
It's not a bug in R. It seems to be a docmentation error or infelicity in xtable: it clearly does not work with all data frames, and the restrictions are neither clear to me nor enforced. Please take it up with the xtable maintainer.
