[R] i'm so stuck with text file and contour plot

I think he may also need to add the header=TRUE argument:

tdat <- read.csv("http://www.nabble.com/file/p24777697/small.txt",  
header=TRUE, sep="\t")

Note: read.table with those arguments should have worked as well.

And then use names(tdat) <- c(<less bloated list of variable names>)

Perhaps along these lines:
tdnames <- names(tdat)
tdnames

#####------don't paste----------
[1] "Placename"
[2] "X_coord"
[3] "Y_coord"
[4] "Jan.to.Dec.2006.Stroke.Density.per.sq.km"
[5] "Jan.to.Dec.2007.Stroke.Density.per.sq.km"
[6] "Jan.to.Oct.2008.Stroke.Density.per.sq.km"
[7] "Total.Strokes.per.sq.km.for.Jan.2006.to.Oct.2008"
#######-------------

  names(tdat)[4:7] <- c("Strk.dens.2006", "Strk.dens.2007", "Strk.dens. 
2008", "cumStrk.2006_8")

            # cannot use variable names that begin with numbers  
without special efforts
tdat       # now can be displayed more economically
