[R] Order labels in qplot() - ggplot2 {help}

Hello, I want to arrage the label according to my preference eg.. (va, vp, a, b, c) but don't know how to supress default ordering. Any suggestions? Please try the code below: n <- c("va", "vp", "a", "b", "c") p <- c(2, 2,1, 3,5) pm<- c(3,4,2,5,4) pn <- c(1,1,1,2,3) x<-data.frame(cbind(n,p,pm,pn

Re: [R] bug? in stats::cor for use=complete.obs with NAs

I don't think that this would be considered a bug. The reason for the discrepancy between use="complete.obs" and use="pairwise.complete.obs" for the case of the Spearman correlation of two vectors x, y is this: "pairwise" does complete.cases(x,y) and then ranks; this is also what's done in cor.te

Thanks, Actually, thanks to the info Henrique sent, I have made decent progress. In actuality, I could have just submitted a SELECT * on the second table, which would give me everything, just like Henrique's suggestion, and yours, would give me. The problem is that that table is HUGE (I don't wa

Re: [R] Order labels in qplot() - ggplot2 {help}

Hi, You could reorder the factor levels before plotting, x$n = factor(x$n, levels=c("va","vp", letters[1:3])) last_plot() %+% x or you could avoid using factors in the first place, x <- data.frame(cbind(n,p,pm,pn), stringsAsFactors=FALSE) last_plot() %+% x HTH, baptiste On Thu, Jun 10, 20

Ted I'm not sure I fully understand the question, but you may want to consider creating a temporary table with a join, which you can do with a query from your R session, and then query that table to bring the data into R. Roughly, the logic is to leave the data in the db if you are not doing an

[R] setting the current working directory to the location of the source file

AFAIK a script run through source() does not have any legit way to learn about it's own location. I need this to make sure that the script will find its datafiles after I move the whole directory. (The datafiles are in the same directory.) Here is a hack I invented to work around it: print(getwd

Hi I am not sure if you can do what you want. Segments are not points so your pch option is (I believe) ignored. You could play with lmitre and lend parameters, but it probably would not help much. You cold try to look at ?symbols but you probably need to change source code to suit your needs.
