Dear Rxperts! Below are relevant lines of code, I am having problems with.. I am not sure if it is a bug in R or OS related or something else... When viewing the pdf file, I notice overlaid plots in a panel of the plot are shifted to the right. The Y-axes and X-labels are not exactly on top of each other. Would highly appreciate your suggestions..
