How do I assemble ad data fame, consisting of columns form other data
frames identified in a loop? cbind is not working as the initial data
fame has 0 columns and rows.
> ModList<-dir("./MODEL_DISTS/")
> ModList<-ModList[grep(pattern="3COLUMNS",ModList)]
> ALL_MODELS<-data.frame()
> for (i in ModList){
+ X<-read.table(file=paste("./MODEL_DISTS/",i,sep=""))
+ BASE=sub("3COLUMNS","" , i, fixed = TRUE)
+ names(X)<-c("FromSiteID","ToSiteID","CS_RESISTANCE")
+ ALL_MODELS<-cbind(ALL_MODELS,X[3])
+ }
Error in data.frame(..., check.names = FALSE) :
arguments imply differing number of rows: 0, 2080
thanks
