Hi there, This is a problem I've run into and do not know how to avoid. It happens when I make an assignment using the dimension names as the subscript of the array. The end result is a dimenensionless array (i.e. a vector) which I don't want. See:
> out <- array(0, 5, list(1:5)) > dim(out) [1] 5 > out[names(out)] <- 1 > dim(out) NULL I tried to include a 'drop' argument into the index but it doesn't seem to work: > out[names(out), drop=FALSE] <- 1 Error in out[names(out), drop = FALSE] <- 1 : incorrect number of subscripts on matrix A solution would be to change the vector into an array myself, but I would like to hear opinions before I do that, because I would rather just make the assignment and keep the array object unchanged if such thing is possible. Also, using a subscript of integers instead of labels is not an option in this case. Any help appreciated. -- Cheers, Ernest ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
