downloadData: Download data and read into R

In pbreheny/hdrm: High-Dimensional Regression Modeling

Download data and read into R

Description

These functions are downloading, reading, and attaching data sets described in the hdrm book. To keep the size of the hdrm package manageable, these data sets are not included with the package and must be downloaded separately using downloadData(); this only needs to be done once.

Usage

downloadData(name)

readData(name)

attachData(name, envir = parent.frame())

Arguments

name	Name of data set to read/attach
envir	If attaching, to which environment?

Details

Data sets in hdrm are lists consisting of X, y, and possibly other elements. readData returns the list as an object that the user can name and use how they want. attachData assigns the elements of the list into the user's environment. attachData is often more convenient, but offers less control and potentially introduces side effects, such as overwriting an existing object X if one already exists. See the examples for more details.

Examples

## Not run: 
downloadData()         # Download all data sets
downloadData(brca1)    # Download a specific data set
## End(Not run)

Data <- readData(brca1)
dim(Data$X)
head(Data$y)


attachData(bcTCGA)
dim(X)
head(y)
