Hello -
I have noticed that when I run svm() the order of my data matters. If the
first case in the data frame has y=+1 I get the expected decision rule that
says to classify as +1 if f(x)>0. However, if the first case in the data
frame has y=-1 then apparently the decision rule being used says
I have a grid data which has values of a variable (e.g: Temperature). My
data has 6069 data points where each data point refers to different
latitude and longitude. I want to transform this data to a raster file so
that I can clip it according to a shapefile that has much smaller
boundaries than th
Thanks all for the clarification!

The only thing "compelling" about your example is that you have the
pre-conceived (wrong) notion that you have to store your objects under
separate names in your global environment. That is not only wrong, it
handicaps you for future unified processing of these data.

Bendy like spaghetti :-) Thanks, Jim. I wasn't aware of plotrix, and
it does seem to be a cornucopia of useful, graphical stuff.
In this case, my quest for rotating characters stemmed from what you
might call a PHB request that I was eventually able to work around. I
posed my original question
Hmm. Thanks, Paul. That would explain the dearth of examples.

Thank you very much, and your reply is helpful.
I don't like assign, and even don't use parse in my previous codes.
However, in the case I encountered, assign and parse may be the right
tools. Here is the code I used:

Hi Michael,
The arctext function (plotrix) does something similar, and the code
could be modified to do what you request. If you do want a working
function, it wouldn't be too hard to program.

Hi

no user-level functions ever refer to it either. In other words, it

Hard to know what you want or did without code.
But, a guess: did you want the "srt" parameter and not "crt"?
Of course, it's always useful to read the man page, in this case for
?par, where it says:

Hi, folks. This is an issue that we've defined away, but I recently
thought it would be useful to rotate characters in some marginal text
in a base-R plot. I made a few stabs on using the "crt" parameter but
was unsuccessful.
I'm deliberately omitting details of my attempts, as I want just to

Copy your queries to the help list. Do not use html (google "send plain text

Thank you everyone for all your help. Dr. Therneau and I had some offline email

reduce the computational overhead in resampling scenarios such as mine. It will

I debated saying something similar but decided not to, as polygons can
be drawn e.g. via panel.polygon.

It is not a question of whether lattice "understands" the unsorted data...
imagine trying to plot 4 points to form a square instead of a trend line... you
would NOT want lattice to sort those points for you. That lattice leaves your
data alone gives you more flexibility, even while it adds work

Yes. type = "l" connects the points in the order given in the data, so
if the x's are not already ordered, the plots will be different after
ordering the x's.

That looks like an error from Stan parsing your stan file, but the

Dear all, I am new to lattice, so would appreciate anyone's help on the
