Just 2 more questions - for now!
...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!

dataset is fairly large (1530 observations). I simply want to model the
response against a lag of a couple of the explanatory variables, say
maxitemp and rainfall. I would like to look at lagtimes of 4 days, i.e.
4 observations....

Using if, else statements
Hi all,
Again I have searched the net and so on, without finding an answer to this
surely simple problem. A short bit of code would be appreciated.
I have a object named `data' with the following column headings.
Date, maxitemp, minitemp, admissions, d.o.w.
Where d.o.w. is day of the week, written "Sun" "Mon" etc.
I just need to scale the Monday admissions by 0.91, the Saturday
admissions by 1.21 and the Sunday admissions by 1.22. So basically what I
want is:
If d.o.w. == "Sat"
