Q1:
Have a look at: ?save ?save.image ?load Q2: I am not sure this is right: model<-lm(data$admissions~data$maxitemp) Try and code a line that looks more like this with the variables the names of the columns in your data: model<-lm(admissions ~ maxitemp + minitemp, data=data) Have a read of ?formula for more information. (I usually try and avoid using the name "data" for my data because data is a function in R.)

Hi all, Thanks for the help with my previous post. I have just two more questions for the minute. I think I said in a previous post that I like to use the terminal, i.e. run rterm.exe. On exiting the terminal, I am asked if I want to save the workspace. If I hit y (yes), the workspace is just saved as .rdata in my working directory, does anyone know how I can name it directly from the terminal? More importantly, I can't then open this file from the terminal. Obviously loading the file from windows explorer brings up the GUI. Anyone know the command I need? All I can think of doing is adding rterm.exe to my path and running it from the command prompt (adding the file as an argument to my command), but surely there is an easy way to do this from R? Of course I would like to have the terminal open and open and close various workspaces in one session, without wanting to restart R all the time. Finally, I rather embarrasingly can't get lm to work despite reading the help. I can get it to work with a single explanatory variable, EG model <- lm(data$admissions~data$maxitemp) but how to include a second explanatory variable (minitemp)? I keep getting errors. Surely I don't need to use c(data$maxitemp,data$minitemp) etc? All help greatly appreciated - I am getting there slowly!
