In your first example you created logfat.lm and then tried to plot logfat so you got an error indicating that logfat did not exist.
In your second example we have no idea what body.fat. You must make your examples reproducible so that we can reproduce your error. It looks like you could also benefit from spending a little time learning about R using a free tutorial. ------------------------------------- David L Carlson Department of Anthropology Texas A&M University College Station, TX 77840-4352 -----Original Message----- From: R-help [mailto:r-help-boun...@r-project.org] On Behalf Of Ian Lester Sent: Monday, March 30, 2015 12:59 AM To: r-help@r-project.org Subject: [R] Again: A problem someone should know about i have no idea what to do > plot(body.fat, BMI,xlab="Body fat",ylab="BMI",main=“Figure 2.1: BMI vs Body > fat (n=252)”) Error: unexpected input in "plot(body.fat, BMI,xlab="Body fat",ylab="BMI",main=�" > plot(body.fat, BMI,xlab="Body fat",ylab="BMI") serious error.
