Good Morning 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$RES_ID) res E000- 0 F160- 0 XFRT- 33 XVVR- 0 SWEX- 23 SWRS- 0 just wanted to see the data with values greater than 0 in the example only two results because when create the graph create empty space barplot(table(x.sub$RES_ID),width =1,angle=45,inside = TRUE, plot = TRUE, axis.lty = 0, offset = 0,add = FALSE, main="hist C",col=rainbow(x.sub$CALLEDSTATIONID)) Thanks -- View this message in context: http://r.789695.n4.nabble.com/Subset-problem-tp4452837p4452837.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
