Hi everyone
Since I updated package 'ffbase', subset.ffdf does not work with bit vectors
anymore. Here is a short example:
data(iris)
library(ffbase)
iris.ffdf <- as.ffdf(iris)
index <- sample(c(FALSE,TRUE), nrow(iris), TRUE)
index.bit <- as.bit(index)
subset(iris.ffdf, subset=index.bit)
results in the error message:
Error in which(eval(e, nl, envir)) : argument to 'which' is not logical
My code was working prior to the update...
and help on subset.ffdf sais:
subset: an expression, ri, bit or logical ff vector that can be
used to index x
Any help would be highly appreciated.
Many thanks
Christian
