[BioC] read.maimages & wt.fun

[gb606342000]

Dear All,

I am having problems to import genepix files. Does anyone have
an idea what is going on? I use Mac OS X version 10.5.8.

Please, see below.

Thanks. Giovani


This code DO NOT work:
> f <- function(x) as.numeric(x$Flags > -1) 
> RG <- read.maimages(targets, source = "genepix", other.columns=list("Flags"), wt.fun = f)
Error in gsub("\\.", "\\\\.", x) : 
  input string 1 is invalid in this locale

Removing the "wt.fun = f", works fine:
> f <- function(x) as.numeric(x$Flags > -1) 
> RG <- read.maimages(targets, source = "genepix",  other.columns=list("Flags"))
