[R] scatter plot matrix with different x-y variables

[John Kane]

Several ways but I find that grid.arrange in the  gridExtra package combined with ggplot2 to draw the actual graphs works nicely.

You might also want to look mfcol or mfrow in ?par 

### quick and dirty example of ggplot2/gridExtra

library(ggplot2)
library(gridExtra)

mdat  <-  data.frame(a= 1:5, b=1:5)
ndat  <-  data.frame(x = rnorm(20), y =  rnorm(20))
p  <-  ggplot(mdat  , aes(a,b, colour = 'red'   )) + geom_point() +
            theme(legend.position="none")
          
        
p 
q  <-  ggplot(ndat , aes( x, y  )) + geom_line() 
q

grid.arrange(p, q)
###  
I imagine that you will need to install the ggplot2 and gridExtra packages. See ?install.packages for help
