Added two new optional arguments to nsplit: * keep_empty: if set to false empty elements are not stored in the returned list. The default is to keep the empty elements * count: specifies how many splits to perform; negative count (the default) means do as many splits as possible Added tests for nsplit.

Dear R-devel, I am trying to alter rpart so that it makes additional calculations when growing the tree. In the "rpart.s" there is a call to the C routine: rp <- .C("s_to_rp2", as.integer(nobs), as.integer(nsplit), as.integer(nodes), as.integer(ncat), as.integer(cats *!isord), as.integer(max(cats)), as.integer(xval), which = integer(nobs), cptable =...

Hide/prevent the use of bad string functions like String.lowercase. These are replaced by safe functions that won't break UTF-8 strings. Other miscellaneous refactoring. Rich.

Dear R-list members, I am doing a CART analysis in R using the rpart function in the rpart package: Phrag.rpart=rpart(PhragDiff~., data = Phrag, method="anova", xval=10).
