Hi, type ?plot [Enter]and click the "par" link in the first line. This takes you to all the parameters you can set for plot commands. The one you are looking for is:
xaxs The style of axis interval calculation to be used for the x-axis. Possible values are "r", "i", "e", "s", "d". The styles are generally controlled by the range of data or xlim, if given. Style "r" (regular) first extends the data range by 4 percent and then finds an axis with pretty labels that fits within the range. Style "i" (internal) just finds an axis with pretty labels that fits within the original data range. Style "s" (standard) finds an axis with pretty labels within which the original data range fits. Style "e" (extended) is like style "s", except that it is also ensures that there is room for plotting symbols within the bounding box. Style "d" (direct) specifies that the current axis should be used on subsequent plots. (Only "r" and "i" styles are currently implemented) Cheers, Daniel ------------------------- cuncta stricte discussurus ------------------------- -----Ursprüngliche Nachricht----- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Im Auftrag von Enrico Rossi Gesendet: Monday, April 14, 2008 6:57 PM An: r-help@r-project.org Betreff: [R] Plotting with exact axis limits Hello, If I make a plot, say something simple like plot( runif(100) ) then the origin (0,0) is not at the bottom-left corner of the box surrounding the plot. The axis limits are "padded" slightly. This is ordinarily a good feature, because it makes plots look better. But now I would like to make a plot with the origin exactly on the bottom left. Through trial and error, I have discovered that this padding is approximately 3.8% of the axis length. That is, plot( runif(100), ylim=c(.038,1), xlim=c(3.8,100)) gives the desired result. However, this seems like a rather inelegant hack. Is there a "correct" way to do this? Thank you!
