Hi, I am currently building graphs using dochart(). I plotted the points in two different colors according to specific criteria from my dataset. Later, I decided to also give them different symbols, for easier reading if printed. I got quite a surprise when I realized that, even though I gave the same variable to both color= and pch= , I got a mix of the colors and symbols. I wanted one type of symbol to be only one color, and the second only the other color, and it is clearly not what happened. From my data, I would say that the pch= argument is not dealing properly with the variable I gave it. I tried using a dataset from R to see if this was only in my dataset, and it did the same. here’s a reproducible example, using beaver1:
dotchart(beaver1$temp, groups=factor(beaver1$day), color=as.factor(beaver1$activ), pch=beaver1$activ) Does anyone know why, with the same variable, the arguments color & pch give different results? That would be of great help, since now I am no longer sure which one isthe correct representation of my data. Best regards & many thanks for the help Simon Gingins ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
