an object to identify a file in package/subdir via sprintf(fmt, x).
For example, the default 'fmt' translates x = 2 into 'ch02.R'. If
no 'x' is specified, a directory of options is provided.
CAUTION: Under some systems like ESS (Emacs Speaks Statistics)
under Windows, pop-up menus such as produced by 'runscript()' may
not work properly.
method
One of the following:
run
run the desired script file, similar to demo or
example.
copy
make a copy if the desired script file in the working directory,
similar to Stangle(vignette(...)[["file"]]).
view
display the desired script file on R console but do not execute it.
show
display the desired script file using file.show
dir
return the directory showing only the location of the desired
script.
Partial matching is allowed.
ask
logical: Should 'par(ask=TRUE)' should be called before graphical
output happens from the scruot?
fmt
a format to be used with 'x' in sprintf to create the name of
a file in lib.loc/package/subdir.
subdir
subdirectory of package containing a file of the name constructed
via sprintf(fmt, x)
package
Name of a package with subdirectory 'subdir'.
lib.loc
NULL or character string identifying the location where
'system.file(subdir, package, lib.loc)' will find the folder
containing the file identified via sprintf(fmt, x)
Details
similar to demo or example
Value
the full full path and filename, invisibly unless method == 'dir'
## Not run:
# provide a menu
runscript()
# run ~RlibraryFinTSscriptsch01.R
runscript(1)
# same as:
runscript(1, "run")
# make a copy as 'ch01.R' in the working directory
runscript(1, 'copy')
# display on console only
runscript(1, 'view')
# display using file.show
runscript(1, 'show')
# where is it?
runscript(1, 'dir')
# run ~Rlibrary\nlmescriptsafda-ch01.R
