将函数内的 .rmd 数据文件加载到环境中

Question

I'm new to functions and I would like to load my data with a function. The function appears to be correct but the file does not save as a dataframe to the environment, while this does happen when it's not within the function.

This is my script:

read_testdata <- function(file) {
  Dataset_test <- read_rds(here("foldername", file))
}

read_testdata("filename")

Can someone spot my error?

Answer 1

After some thinking I spotted my problem, the correct code should be this:

read_testdata <- function(file) {
 read_rds(here("foldername", file))


}

Dataset_test <- read_testdata("filename.rds")
