I have very large data sets given in a format similar to d below. Converting

Any ideas?

You have 3 Ys and your original email indicated at least

Dear,
I am a newbie to R.
I am trying BIOMOD to simulate species distributions with presence-only
data.
As the presence-only data consist of three columns, presence, longitude,
latitude,
please kindly share how to prepare the background data (maybe using ArcGIS
?)
Thank you

Dear Dieter,
Thanks for the info.
However, I did not know which document you refer to.
Please kindly indicate the website or the source.
Thank you

You might have a look a Alejandro Jara DPpackage which worked quite well for
me in a similar case.

Hi L.A.,
Use the package 'hwriter' to produce HTML pages/objects.

'hwrite' can be combined with the function 'format' (to manage number
format, digits, decimal places, etc...) and supports advanced HTML/CSS
formatting opt

Dear all,
I'm currently applying a mixed model approach to meta analysis using the
package metafor. I use the "model.matrix()" function to create dummy
variables. The option btt gives me the combined test for the dummies.
Problem is, I don't know which indices I have to use, and can't really

Good Morning Prof. Ripley:
Thanks very much for the help. I do have the Davison and Hinkley text but I
continued to struggle with the proper syntax to make iteration work. The MASS
package is already installed on my machine and I have the manual so I will
check the example you mentioned.
Thank

You can probably add SciViews in the list. There are many, many
interesting features in SciViews-K/Komodo for developing new user
interfaces rapidly and easily. Unfortunately, there is no documentation

Dear all,
I'm attempting to use a piecewise regression to model the trajectory
of reproductive traits with age in a longitudinal data set using a
mixed model framework. The aim is to find three slopes and two points-
the slope from low performance in early age to a point of high
performan

Try "spectrogram" in r-help search.

Hi Dennis and Gabor,
Thanks a lot for the useful suggestions!
Cheers!!
