Dear all, I am preparing a graph in which values derived from 2 variable are displayed using the stripchart function. I have applied the factor function to separate the 2 variables in two groups, although I noticed that the graph works anyway even without the factorisation of the variables. However there is a lot of space between the two factors, thus most of the graph is empty. It is possible to reduce the space between the factors? The function I have implemented is more or less like this: stripchart ( Y ~ factor(X), method = "stack" , offset=1/3, vertical = TRUE, las=1, pch=19, ylim=Y, xlim=c(1, 2), par(mai=c(1,1,0.5,0.1)) ) Best regards Luigi [[alternative HTML version deleted]]
