To the R experts,
I am currently playing with a program which was designed so that the
outputs
are to be read in "Surfer". I do not have the program, but the
files, can
but put into excel and graphed. I figured i could do the same thing
with R.
If I open the file with excel, and put the text into columns,
Generally lines are read in as rows, but if you have all all numerics,
then it would be a fairly simple matter to make a data.matrix and
transpose.
and separate them by spaces,
No need to "separate by spaces" since any white space will be
considered as a separation.
I can then graph it. But how do I do this in R?
It would help if you would be more precise and especially if you would
attach a text file.
Once I have
done all that in excel and saved it, I can then open it and do a 3d
suface
plot in R, but I would like to skip the excel step.

The first thing I have to do is remove the first 4 lines (which are
just
file information),
The read.table function has a skip argument:
?read.table
Perhaps:
dta <- read.table(file="/wherever/whatever.txt", skip=4)
and then separate each value
"Each value into its own column" would be the default action ... if
there were no line feeds. which is not possible to determine from what
you presented..

into its own column. How do
I go about doing that?
Cheers lads.
