I am confused about the output from a lm() model with an incomplete
design/missing level.
I have two categorical predictors and a continuous covariate (day) that
I am using to model larval mass (l.mass):
leaf.species has three levels - map, syc, and oak
cond.time has two levels -

Hi David -
Looking at the package documentation I see this:
maxent: A list containing the location of the MAXENT application and
its input files (see
details).
Maybe I was wrong about 'spec' and the malformed argument is 'maxent'.
If I had been constructing it I would have created a
dumpMethods('diag', file='diag.R')
readLines('diag.R')
character(0)
I appreciate the alternative suggested by Ceci Tam, but is this
result a feature or a bug?
More generally, what do you recommend I read to learn about S4
generics? I've read fair portions of Chambers
Hello,
What is the fastest way to do this? I has to be done quite a few times.
Basically I have sets of 3 numbers (as characters) and sets of 3 dashes and
I have to store them in named columns. The order of the sets and the column
name they fall under is important. The actual numbers and the
R programming question, not machine learning, although that's the content.
Apologies to all for whom the following code is eye-burning. I am using
foreach() to run a simulation on a randomForest model (actually conditional
randomForest ... party package). The simulation is in two dimensions.
Ben -
There are most likely faster ways, but
matrix(apply(matrix(rep_vec,ncol=3,byrow=TRUE),1,paste,collapse=''),
ncol=4,byrow=TRUE,dimnames=list(NULL,nms))
seems reasonably fast. (Do you really mean 4 columns and *5* rows?
With rep_vec = rep(vec,times=20), I get 25 rows.)

Hello,
Try
vec = c(1,2,3,-,-,-,4,5,6,1,2,3,-,-,-)
nms = c(A,B,C,D)
rep_vec - rep(sapply(split(vec, cumsum(rep(c(1, 0, 0), 5))), paste,
collapse=), 4)
mat - matrix(rep_vec, nrow=5, byrow=TRUE, dimnames=list(NULL,nms))
mat
Hope this helps,

Yes. There are only about 16 significant digits in (64 bit) floating point. One
Thanks for your help -- you were absolutely correct. And I apologize
for the poor nomenclature -- when referring to versions I always just
say 'fifteen' or 'twelve point one', so it is too easy to forget the
leading '2.' when typing. Careless of me.
Cheers,

I'm checking out Phil's solution...so far so good. Thanks! Yes, 25 not 5
rows, sorry about that.
Rui - I can't modify rep_vec...that's just sample data. I have to start
with rep_vec and go from there.
have a good weekend all...
