Hi,
I am reading numeric data as below but the problem is the object ndata1 and
nd1 have characters instead of numeric values. I want to keep it as numeric.
Why the type has changed from numeric to character and how to avoid this
problem?
rdata1<- read.table(file="data1.txt", header=F,stringsAsFactors=F)
>rdata1
V1
1 d1
2 11
3 20
4 13
rdata2
V1
1 d2
2 1
3 7
4 5
5 6
>ndata1<-rdata1[2:nrow(rdata1),]
> ndata1
[1] "11" "20" "13"
>nd1<-cbind(ndata1,v2=0)
> nd1
ndata1 v2
[1,] "11" "0"
[2,] "20" "0"
[3,] "13" "0"
