Hello everyone. How do I get R to ask users for data to be entered? Specifically I want to ask for a z score to be entered (the user would look this up in a table) and then use the entered data to compute a Dunn's post-hoc test (post kruskal.test). I've tried the "ask" function but it's not recognised - maybe I don't have to appropriate libary installed. A pointer to the right one would be appreciated. e.g >z <-ask(message="Please enter the z value for" x) Any help would be gratefully received. Thanks Iain Gallagher Institiute for Infection and Immunology Research Edinburgh University
Dear Iain,
There's an ask() function in the sm package that does what you want, but
you'll have to compose your message properly: ask(paste("Please enter
the z
value for", x))
Alternatively, eval(parse(text=readline(paste("Please enter the z value for
", x, ": ", sep="")))) will do what you want, as would
as.numeric(readline(paste("Please enter the z value for ", x, ":
",
sep=""))).
I hope this helps,
John

library(sm)
> z <- ask(message="Please enter the z value for")
Please enter the z value for: 1.96
> z
[1] 1.96
I found this using RSiteSearch("ask",
restrict="functions") .

Use readline for a text dialog or use tkentry from the tcltk package as shown in the Edit Box example at: http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/ On Windows other possibilities exist as well: winDialogString and in package svDialog there is guiDlg . Also check out qnorm . On 10/16/05, Iain Gallagher <iaingallagher at btopenworld.com> wrote:> Hello everyone. > > How do I get R to ask users for data to be entered?
