transmuteAt(object, vars, fun, ...)

## S4 method for signature 'DFrame,function,function'
transmuteIf(object, predicate, fun, ...)

Arguments

object	Object.
fun	function. Mutation function.
...	Passthrough arguments to function declared in fun argument.
vars	character. Column names.
predicate	function. A predicate function to be applied to the columns. For example, is.atomic().

These functions are inspired by dplyr. However, they are designed to only work on Bioconductor S4 class objects, and use base R code internally.

Examples

data(mtcars, package = "datasets")

## DFrame ====
x <- as(mtcars, "DFrame")
mutateAll(x, fun = log, base = 2L)
mutateAt(x, vars = c("mpg", "cyl"), fun = log, base = 2L)
mutateIf(x, predicate = is.double, fun = as.integer)
transmuteAt(x, vars = c("mpg", "cyl"), fun = log, base = 2L)
transmuteIf(x, predicate = is.double, fun = as.integer)
