One generally useful piece of advice would be to avoid using 'attach'. Instead, try 'with' Amend your data frame, and then do something like with(machm, plot(xmach,ymach, xlim=c(-5,5),ylim=c(-5,5), pch=19, cex=area*0.05,col=coll)) That will make sure that the items mentioned in the plot() call are taken from the data frame that you have just amended. In your original code, you attached the data frame, making a copy of its contents available to the global environment, then you modified the attached version of the data, and then told the plot() command to use the original (unamended) data in the data frame. That is an easy mistake to make when using 'attach', and a good example of why it's better to use 'with' instead of being unsure which copy of the data is in use. > -----Original Message----- > From: r-help-boun...@r-project.org > [mailto:r-help-boun...@r-project.org] On Behalf Of Ashok Parmar > Sent: 12 August 2012 03:54 > To: r-help@r-project.org > Subject: [R] "Masked by GlobalEnv" > > hello everyone, > i am getting problems in graph plotting.
