Wrappers for dirname, file.choose, readLines. file.create, file.path to be called directly for listing directories, creating files, showing the files in a directory, and listing the content of files in a directory. fileCreate gives the functionality of file.choose(new=TRUE). filesList combines file.choose, dirname, and list.files to show the files in a directory, fileScan extends this and then returns the first few lines of each readable file
fileScan(f = NULL, nlines = 3, max = NULL, from = 1, filter = NULL)
filesList(f=NULL)
filesInfo(f=NULL,max=NULL)
fileCreate(newName="new.file")File path to use as base path (will use file.choose() if missing. If f is a directory, will list the files in that directory, if f is a file, will find the directory for that file and then list all of those files.)
How many lines to display
maximum number of files to display
First file (number) to display
Just display files with "filter" in the name
The name of the file to be created.
Just a collection of simple wrappers to powerful core R functions. Allows the user more direct control of what directory to list, to create a file, or to display the content of files. The functions called include file.choose, file.path, file.info,file.create, dirname, and dir.exists. All of these are very powerful functions, but not easy to call interactively.
read.file to read in data from a file or read.clipboard from the clipboard. dfOrder to sort data.frames.
# NOT RUN {
#all of these require interactive input and thus are not given as examples
#fileCreate("my.new.file.txt")
#filesList() #choose the items in the directory where a file is displayed
#fileScan() #show the content of the files in a director
#or, if you have a file in mind
# f <- file.choose() #go find it
#filesList(f)
#fileScan(f)
# }
