WebThe output r is a vector of length n.In particular, r[i] is the distance between X[:,i] and Y[:,i].The batch computation typically runs considerably faster than calling evaluate column-by-column.. Note that either of X and Y can be just a single vector -- then the colwise function computes the distance between this vector and each column of the other … WebExamples. # Count number of missing values nmissing <- function(x) sum(is.na(x)) # Apply to every column in a data frame colwise (nmissing) (baseball) # This syntax looks a little … impact of early years education

WebMutate multiple columns. Scoped verbs ( _if, _at, _all) have been superseded by the use of pick () or across () in an existing verb. See vignette ("colwise") for details. The scoped variants of mutate () and transmute () make it easy to apply the same transformation to multiple variables. There are three variants: WebC++ (Cpp) MatrixXd::colwise - 30 examples found.
