ImportDlg: Get Path of a Data File to Be Opened

Description

Handling of pathnames is tedious in Windows because of the backslashes, that prevent simple pasting of a copied path into the source code. ImportDlg displays the FileOpen-Dialog for picking a file interactively. When done backslashes in the path are replaced by slashes and the result is being copied into the clipboard, from where it can easily be pasted in any code editor.

Usage

ImportDlg(fmt = 1)

Arguments

fmt

the format, in which the filename parts should be returned. Default ist path\filename.ext and coded as ""%path%\%fname%.%fxt%"". See examples for time saving alternative definitions.

Value

• ImportDlg() invisibly returns the path of the chosen file in the defined format. The result is additionally being copied to the clipboard.

file.choose

Examples

# choose a file
fn <- ImportDlg()
print(gettextf("You chose the file: %s ", fn))

# the path and filename can as well be nested in a command,
#   done here to build a read.table command that can be well inserted into the code:
ImportDlg(fmt="d.%fname% <- read.table(file = \"%path%\%fname%.%fxt%\", 
  header = TRUE, sep = \";\", na.strings = c(\"NA\",\"NULL\"), strip.white = TRUE)")

# go to your editor and paste...
