read_list: Read a lot of datasets at once with R

In emilelatour/lamisc: Latour's Little Helpers

Read a lot of datasets at once with R

Description

Supply a list of data sets and the function to read the datasets. For example, to read in .csv files, use readr::read_csv. This function comes from Bruno Rodrigues' website and credit goes to him.

If you prefer not to have the datasets in a list, but rather import them into the global environment, then use read_list2.

Usage

read_list(list_of_datasets, read_func)

read_list2(list_of_datasets, read_func, envir = .GlobalEnv)

Arguments

list_of_datasets	A character vector with names of data sets to read.
read_func	Function to read the data sets.
envir	Environment to assign data frames to. Default is .GlobalEnv. Used in read_list2 only.

Value

A list of data sets
