Hello, I was wondering how to call a function outside a setRefClass but inside the package without export it. Let me explain by means of an example.
- in the file test-package/R/test.R ##' some description ##' ##' some details ##' @title test ##' @return sideeffect ##' @author Jeremie Juste ##' @export test ##' @import data.table test <- setRefClass("test", list(dt="data.table")) test$methods( initialize = function(x){ dt <<- remove_if_all_na(x[,abc:=1]) } ) ##' remove rows for which all values are NA ##' ##' @title remove_if_all_NA ##' @param dt ##' @return dt ##' @author Jeremie Juste remove_if_all_NA <- function(dt) { cn <- colnames(dt) dt[!dt[NA],on=cn] } Here when I build and install the package test-package, if I don't export remove_if_all_NA ##' remove rows for which all values are NA ##' ##' @title remove_if_all_NA ##' @param dt ##' @return dt ##' @author Jeremie Juste ##' @export remove_if_all_NA <- function(dt) { cn <- colnames(dt) dt[!dt[NA],on=cn] } The package cannot use it. library(test-package) library(data.table) > aa <- data.table(a=1:10,b=letters[1:10]) > b <- test(aa) Error in remove_if_all_na(x[, `:=`(abc, 1)]) : could not find function "remove_if_all_na" Do you have any recommendations? The official documentation for setRefClass is a bit thin for me but I wanted to use a tools that is going to stay. Any tip is welcome.
