hello

I want to compare the values of two columns of a dataset on a graph. 
Which graphic do you recommend ?

It depends on what values you have and what you want to compare.

plot(x,y) 

boxplot(x, y)

There are plenty other options in R.

Hi Petr,
"barp" will compare the two columns displaying the values as heights of 
bars.

"stackpoly" will display superimposed polygons, the upper edges of which 
represent the data values in each column.

"twoord.plot" will dislay two data vectors as point/line plots even if 
they have different ranges.

All are in the plotrix package.

When it comes to these, I prefer plot(y~x, data=dataset), since it  
picks up the correct graph depending on what types the variables have.
