performance issue with merge
...200 2.71 NA 1.34
ID1_300 0.92 1.22 NA
...
Merging works as long I do not set the all.x and all.y directive in the
merge command:
DF <- data.frame(NULL)
count=0
filenames <- list.files()
filenames
for(i in filenames) {
count<-count+1
tmp <- read.delim(i, header=FALSE)
rwnames <- paste(tmp[,1], tmp[,2], sep="_")
tmp<-tmp[,3]
tmp<-as.matrix(tmp)
rownames(tmp)<-rwnames
if (count == 1) {
DF <- tmp
} else {
DF <- merge(DF, tmp, by="row.names",all.x = TRUE, all.y = TRUE)
rownames(DF)<-DF$Row.names
DF<-DF[,2:ncol(DF)]
}...

Attributing values to matrix according to names
Dear R-helpers
Apologies for the basic question, but I just got stuck:
I would like to write values from a vector into array cells with the
same names
> count[1:10]
10010 10014 10015 10017 10030 10080 10100 10230 10250 10280
0 0 0 0 0 1 1 0 2 0
>data[1:10,,1]
