This function downloads and makes ready to use datasets from the main
web site for the Hmisc and rms libraries. For R, the
datasets were stored in compressed
save format and
getHdata makes them available by running
after download. For S-Plus, the datasets were stored in
data.dump format and are made available by running
data.restore after import. The dataset is run through the
cleanup.import function. Calling
getHdata with no
file argument provides a character vector of names of available
datasets that are currently on the web site. For R, R's default
browser can optionally be launched to view
html files that were
already prepared using the Hmisc command
html(contents()) or to view ‘.txt’ or ‘.html’ data
description files when available.
an unquoted name of a dataset on the web site, e.g. prostate.
URL containing the data and metadata files
getHdata() without a
file argument returns a character
vector of dataset base names. When a dataset is downloaded, the data
frame is placed in search position one and is not returned as value of
1 2 3 4 5 6 7 8 9 10 11 12 13 14
