You'll need to store it in a list rather than a vector. library(ggplot2) DF<-data.frame(A=rnorm(12),B=c(1:12),C=rep(c(1:4),each=3)) Q <- list() PAC<-geom_point(mapping=aes(x=A,y=B),data=DF[DF$C==1,]) P<-ggplot()+PAC Q[[length(Q) + 1]] <- P Q[[1]]
You could shorten this into library(ggplot2) DF<-data.frame(A=rnorm(12),B=c(1:12),C=rep(c(1:4),each=3)) Q <- list() Q[[length(Q) + 1]] <- ggplot(DF[DF$C==1,], aes(x=A,y=B)) + geom_point() Q[[1]] HTH, Thierry ---------------------------------------------------------------------------- ir.

I have a lot of plots that i need to store as components of a vector. Here you have an example > DF<-data.frame(A=rnorm(12),B=c(1:12),C=rep(c(1:4),each=3)) > Q<-c() > length(Q)<-3 > PAC<-geom_point(mapping=aes(x=A,y=B),data=DF[DF$C==1,]) > P<-ggplot()+PAC > P #generates the plot > Q[1]<-P Warning message: In Q[1] <- P : número de items para para sustituir no es un múltiplo de la longitud del reemplazo > Q[1] [[1]] NULL I guess the problem is the class of Q[1]. if so, what class should I coerce Q to for the sentence: > Q[1] to generate the plot as > P does? thanks in advance [[alternative HTML version deleted]] ______________________________________________ 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.
