Hi all,
i am looking from some insights to define own R functions. so far i
found most basics in documentations that are around on the web. except
for one thing:
I´d like to define some function, say:
#assume my data matrix contains vectors like data$myColumn1,data
$myColumn2 etc.
getMyColumn <- function (columnid){
x<-data$MyColumn?columnid?[data$indexone=1 & data$index2=5]
return(x)
}
Do I need to use assign or eval first ? I tried to use paste to
combine something like: paste("data$MyColumn",columnid,sep="") which
did not work.
I am happy to get any help with the problem, but also thankful for
some useful link or guide on how to define own functions properly,
especially the dynamic naming and return part
thx in advance
bunny
