I''m trying to draw a plot with both the x and y axes starting at zero. However, even with xlim and ylim specified (e.g. plot(x,y,ylim=c(0,800),xlim=c(0,2000)) ), the axes still start just below zero. The lowest x and y values are sufficiently higher than 0 so that having symbols overlapping isn''t a problem. How does one force R to do exactly what you want?

plot(x,y,ylim=c(0,800),xlim=c(0,2000)),xaxs="i", yaxs="i"); see help(par) for details the relevant bit 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 ensured 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) Ian Wilson>I''m trying to draw a plot with both the x and y axes starting at zero. >However, even with xlim and ylim specified (e.g. >plot(x,y,ylim=c(0,800),xlim=c(0,2000)) ), the axes still start just >below zero.
