plot 3d info in 2d
Hi Listers,
Is it possible to produce an ordination plot in 2d, where bubbles represent
the location of sites (this part is easy enough) and the size of the bubbles
is proportional to the sites location in 3d space (I am stuck on this
option). So sites that are very near the 2d plane of the xy axes would be
larger while sites that are actually further away in 3 d space would be
proportionally

ddply from plyr package - any alternatives?
Hello everyone,
I was asked to repost this again, sorry for any inconvenience.
I'm looking replacement for ddply function from plyr package.
Function allows to apply function by category stored in any column/columns.
Regular loops or lapplys slow down greatly because my unique combination
count exceeds 9000. Is there any available solution which allow me to apply
function by category?

R2Cuba package, failed with message ‘Dimension out of range’
Hi All,
I get the message failed with message ‘Dimension out of range’ when using
cuhre in package R2Cuba. Does anyone know what this mean? Or would I need
to email the package author?
The funny thing is it does give a result and comparing it to
"adaptIntegrate" in package cubature, the two numbers are very close.
Thanks,

Just to clarify. I am not offering to pay someone to do my Dissertation.
These 4-5 commands on Kalman Filter would be only a tiny part of my 10,000
words dissertation. A part that even after trying for a few days, I am still
stuck on. I am offering ?50, just to say thanks.
