gsub is looking for a file?

[Gunther Fleerackers]

Hi all,

I'm writing my first shiny app. The purpose is very simple : The user gets 6 numbers and he has to fill in the average. Cause I'm working in Belgium we use comma as decimal. So I wanted to have the user to fill in a number like "27,14" which I want to convert into a numeric 27.14. In R it works fine with the line:

as.numeric(gsub(",",".",answer, fixed=TRUE) 

but when doing this in a shiny app I get a an error :

  cannot open file '12': No such file or directory

Error in file(file, "r") : cannot open the connection

It seems gsub is looking for a file????

How can i get this to work properly?

best regards,

Gunther

You're sure it's precisely that line that's causing that error?

Hi Joe,

You are  right. I rewrote the pice of code and now it seems to work. It's a pity I lost the code of yesterday so i could reproduce the error.

thanks

Gunther
