Hi Jim,
Two thoughts come to me, unencumbered by the thought process or
knowledge of zicounts:
1. Is Poisson really NOT appropriate? (do you have to use zicounts?)
2. Are you 110% certain that all variables are the same length? Would
NA's interfere?

Hi Karen --
This sounds like a Bioconductor question, and should be sent to the

Likely the complaint is about RMySQL being too old, rather than R. The

updating
install.packages(RMySQL, dep=T)
should fix it for you.

ps: The error says RMySQL is the problem... it is not complaining
about R itself (although it would not be a bad idea, given that the

Hi,
Can someone please tell me what such an error message
could mean. i.e where a problem must have arised.
Error in uniroot(function(n) eval(p.body) - power,
c(2, 1e+07)) :
f() values at end points not of opposite sign
Thank you

Hi all,
I posted this question several days ago, but did not get any answer
until now. Since I still have no clue about the source of this error
message, I repost a description of the problem including some code:

Hi all,
A student at our institute asked me for help with the following problem:

Dear R-users,
I am a dentist (so forgive me if my question looks stupid) and came across
a problem when I did simulations to compare a few single level and two
level regressions.
The simulations were interrupted and an error message came out like 'Error

Yu-Kang -
Simulations by their nature use randomly generated data.
Sometimes the random data doesn't contain enough information
to fully determine the parameter estimates for one iteration
or another. It seems likely that that is what happened here.
The design matrix is singular for one

Hello!
Trying to fit a non linear regression model

You should use nls, not nlsModel.
Also, if P is fixed then this is a linear regression model. Why use
nonlinear regression.

There's something special about the way control parameters are
accepted by nlm() and nlme(). Try searching very recent help
archives for nlme() or control. Try duplicating exactly one of
the examples at the bottom of the help page help(nlm). My
recollection is that the parameter
