The online help in R has errors concerning mai and mar.
mai: A numerical vector of the form `c(xb, xt, yl, yr)'
which gives the margin size specified in inches.
mar: A numerical vector of the form `c(xb, xt, yl, yr)'
which gives the lines of margin to be specified on
the four sides of the plot. The default is `c(5,4, 4, 2) + 0.1'.
This would be bad if it were true, since it is different from S-Plus.
However after testing I find that these actually work the same as S-Plus,
so the help should say:
mai: A numerical vector of the form `c(xb, yl, xt, yr)'
which gives the margin size specified in inches.
mar: A numerical vector of the form `c(xb, yl, xt, yr)'
which gives the lines of margin to be specified on
the four sides of the plot. The default is `c(5,4, 4, 2) + 0.1'.
