findPrefix {PBSmodelling} | R Documentation |
Find the prefixes of files with a given suffix in the working directory.
findPrefix(suffix)
suffix |
character vector of suffixes |
The function findPrefix
locates all files in the working directory that end with
one of the provided suffixes. The suffixes may contain wildcards ("*"
to match 0
or more characters, "?"
to match any single character).
If findPrefix
was called from a widget as specified in a
window description file, then the value of a widget named
prefix
will be set to the prefix of the first matching file
found, with an exception: if the value of the prefix widget
matches one of the file prefixes found, it will not be changed.
To use this function in a window description file, the action of the widget is
used to specify the suffixes to match, with the suffixes separated by commas.
For example, action=.c,.cpp
would set a prefix widget to the first file found
with an extension .c
or .cpp
.
A character vector of all the prefixes of files in the working directory that matched to one of the given suffixes.
