Hi,
Try this:
?dat1<-data.frame(V1=c(-9552,0,9614,0,-9752,0,0),V2=c(9552,9653,9614,9527,9752,9883,9865),V3=c("C",0,"V",0,"C",0,0))
?as.matrix(subset(dat1,V3!=0))
#? V1????? V2???? V3
#1 "-9552" "9552" "C"
#3 " 9614" "9614" "V"
#5 "-9752" "9752" "C"
A.K.

Subject: [R] ommoting rows
Hi I have an output data Data.csv
this style:
,"V1","V2","V3"? 1,"-9552","9552","C"? 2,"0","9653","0"
3,"9614","9614","V"? 4,"0","9527","0"? 5,"-9752","9752","C"
6,"0","9883","0"? 7,"0","9865","0"
I want to create a new matrix ommintg all the rows where third column has
0.
There is a way to do it easyly?
Many thanks in advance.
My final matrix will have:
,"V1","V2","V3"1,"-9552","9552","C"
3,"9614","9614","V"5,"-9752","9752","C"
