In the code below test2() gives an error message: Error in .subset2(x, i, exact = exact) : attempt to select less than one element
even though test(), which is nearly the same, gives the expected result. BOD is a data set that comes with R. Is this a bug? idx <- 2 # returns expected result test <- function(pf = parent.frame()) .subset2(BOD, pf$idx) test() # gives error message !!! test2 <- function(pf = parent.frame()) BOD[[pf$idx]] test2() I tried this on Windows Vista under: > R.version.string [1] "R version 2.7.1 RC (2008-06-16 r45949)" and > R.version.string [1] "R version 2.8.0 Under development (unstable) (2008-06-28 r46012)" ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
