Many R programs require multiple input datasets. The purpose of the fetch package is to make it easier to access multiple datasets from an R program. The package allows you to load a catalog of all the datasets in a directory, and then load each desired dataset as needed into your program. The method minimizes the memory used for the data.
The fetch package can be installed from the console. Simply run the following command:
install.packages("fetch")Or if you want the latest development version, you can install it directly from github:
devtools::install_github("https://github.com/dbosak01/fetch")Then put the following line at the top of your program or script:
library(fetch)The fetch package will give you access to a number of functions to import data into your programs more easily and efficiently. For examples and usage information, visit the fetch documentation site here.
If you need help, the first place to turn to is the fetch web site. The web site has full documentation on all fetch functions.
If you want to look at the code for the fetch package, visit the github page here.
