...Here is a reply. When you constructed the data.frame, all strings were converted to factors. If you didn't want that, it would have been possible to specify it: df<-data.frame(a=a,b=b,c=c,stringsAsFactors=F) Then everything would work as intended: one.line<-as.character(df[df$a=="Abraham",]) Actually, the real problem is that df[df$a=="Abraham",] returns a list. There is no need to use as.character here, just unlist: one.line<-unlist(df[df$a=="Abraham",]) The returned list is also the problem with your code. If you have a data.frame with factors, the...

...tially assumed RAC is the problem area. ( Because with both nodes enabled we had terrible performance) Hence we stopped one of the RAC Databases to test out the performance. However even with one node the performance is real bad. Any pointers on how to debug this problem. R'gds Varghese Abraham.

I'm trying to figure out why when I use as.character() on one row of a data.frame, I get factor numbers instead of a character vector. Any suggestions? See the following code: a<-c("Abraham","Jonah","Moses") b<-c("Sarah","Hannah","Mary") c<-c("Billy","Joe","Bob") df<-data.frame(a=a,b=b,c=c) #Suppose I'm interested in one line of this data frame but as a vector one.line <- df[df$a==&...

...e, however the second plot replaces the first one (although it only takes up the upper half as it should): par(mfrow=c(2,1)) a<-sin(1:100) b<-cos(1:100) lag.plot(a) lag.plot(b) What's the trick to this? I'm using R 2.2.1 (2005-12-20 r36812) on Ubuntu Linux.
