search for: val_user

I'm trying to copy the results of a dataframe to another within a cycle for but I am not able to implement the rbind, because give th d<-Null df<-NULL for(r in 2: nrow(x)) { val_user<-x.name[[r]] pos<-x.pos[[r]] -4 age <-x.age[[r]] d<-data.frame(val_user,pos,) print(d) } df<-rbind(df,d) } someone can help me solve this Thanks -- View this message in context: http://r.789695.n4.nabble.com/Copy-dataframe-for-another-tp4456879p445...

...I have a small question regarding the function subset. I am copying data from one table but I just want to collect data from a user. When do I take the view, presents the results I want. The problem arises when can I make the tab. for RES_ID, introduces me to zero results do not envision noVIEW val_user='16' x.sub <- data.frame(subset(Dataset,Dataset$USER==val_user)) View(x.sub) lev_ID<-levels(x.sub$RES_ID) res<-table(x.sub$RES_ID) res E000- 0 F160- 0 XFRT- 33 XVVR- 0 SWEX- 23 SWRS- 0 just wanted to see the data with values ??greater than 0 in the example only two results...
