I'm trying to make correlograms using corrgram. See below for a simple example. #### library(corrgram) data(baseball) vars1 <- c("Assists","Atbat","Errors","Hits","Homer","logSal") vars2 <- c("Putouts","RBI","Runs","Walks","Years") corrgram(baseball[,vars2],lower.panel=panel.shade, upper.panel=panel.pie) #### I am having two problems: 1) I want to change the visual to "bars" (see Figure 1 on p. 3: http://www.datavis....
