Hi meng, A basic display of mosaic plots for all pairs of variables isn't too difficult, but you will probably want to make this a bit fancier. It only displays the unique plots, unlike the "pairs" plot. Keep in mind that "many" variables will mean many plots. chardf<-data.frame(v1=sample(LETTERS[

If there are many character variables,and I want to get the mosaic plot of every pair of each variable,how to do then? If the variables are numeric, I can use pairs to get paired scatter plot. But as to the character variables, how to get the "paired mosaic plot"? Many thanks. -- QQ: 1733

I am plotting three sets of data on a single graph, and doing around 100+ graphs. I can use the expression function to superscript the 2 but that seems to force me to manually put in the R squared values. Is there away around this? This code will show what it should look like this but with the 2

Hi meng, It's not too hard to get a mosaic plot of two character variables: x<-sample(LETTERS[1:3],20,TRUE) y<-sample(LETTERS[24:26],20,TRUE) mosaicplot(table(x,y)) If you could tell us how the above is not what you want, perhaps a better suggestion will appear. Jim On Sat, Feb 7, 2015 at 6:29

If both x and y are all character, paired scatter plot is a little bit strange I think. -- QQ: 1733768559 At 2015-02-06 23:52:34,"Duncan Murdoch" wrote: >On 06/02/2015 6:46 AM, meng wrote: >> Hi all: >> If there are two numeric variable:x,y, and I can get paired scatter plot by >> fun
