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"))
