R Scripts: Templates, Examples of Analyses using knitr
with Rmarkdown
or LaTeX
, Interactive RStudio
Demonstrations | Contents Directory
This is for use with the R function getRs
in the R Hmisc
package for listing available scripts, downloading a selected script, and opening it in the RStudio script editor window.
The special file contents.md
lists all the available files and short descriptions for them. It should not be edited, as it is auto-generated by createContents.r
. contents.md
is used when getRs
is called with no arguments, to give the user a list of available scripts and their descriptions.
The Rmarkdown
scripts included here use a template that makes the result part of a reproducible research process by documenting the versions of R and attached packages at the end of the report. They make use of the Hmisc
package's knitrSet
function. When running Rmarkdown, call knitrSet(lang='markdown')
. knitrSet
gets rid of ## at the start of R output lines, and makes it easy to specify things like figure sizes in knitr
chunk headers. It also causes annoying messages such as those generated from attaching R packages to be put in a separate file messages.txt
rather than in the report.
contents.md
is generated from titles, major and minor categories, and types (R, R Markdown) that are at the top of each script. R Markdown scripts must have suffix Rmd
and have the following information between lines containing ---
and after the output:
section: major
, and minor
(optional). Scripts that fall under multiple categories have those category descriptions separated by semicolons. See descriptives.Rmd
for an example. Regular R scripts must have suffix r
and have the following in the top lines of the script (again, minor
is optional):
# title: Title of Script with Purpose, etc.
# major: major category 1; major category 2 ...
# minor: minor category 1; minor category 2 ...
See introda.r
for an example.
