I'm a developer want to use SystemMl for running R-Code from our business people on a Spark cluster.
I've studied http://apache.github.io/systemml/dml-language-reference
, however, haven't found a implementation of the R function "which" or any alternative functionality. Has anyone an idea how I could
v = c(1,4,NA,2, 5, NA)
# Expect indexes where value meets condition = int 2 5
v2 = which(v>2)
# Expect indexes where is.na returns TRUE = int 3 6
v3 = which(is.na(v))
I've already considered the functions replace() and removeEmpty(), but they don't exactly meets my needs.
Thanks a lot in advance
