Generate and save series of plots with common structure?

[Art Burke]

Consider a data frame with the following structure:

 

df1 <- data.frame(y = runif(10),x1 = runif(10), x2 = runif(10), x3 = runif(10))

 

Is there a way to generate, for example, all the scatterplots of the x’s with y and write them out?

 

Thanks!

Art

Is this what you are looking for?

library("reshape2")
df2 <- melt(df1, id.var="y")
library("ggplot2")
ggplot(df2, aes(value, y)) + geom_point() + facet_wrap(~variable)

Thanks, Brian, but that's not quite what I want. A colleague demonstrated a Stata script that created a series of scatterplots from the data in memory and wrote each of them into a separate file. I'm wondering how to do that with ggplot2.

Something like:

df1 <- data.frame(y = runif(10),x1 = runif(10), x2 = runif(10), x3 = runif(10))

cols = colnames(df1)[-1]

for(i in cols){

ggplot(df1, aes(x=df1[[i]], y)) +geom_point()

ggsave(paste("y_v",i,".pdf",sep=""))

} 

?

Try ggpairs() in the GGally package.

Can someone point me to a ggplot2 example of overlaying images such as in the right side of this one?
