Transforming matrix to data.frame: problems
Hi all,
I have problems transforming a matrix
into a data.frame:
If I do:
> is.matrix(parcelas.cobtot.conti)
[1] TRUE
> dim(parcelas.cobtot.conti)
[1] 25 64
> a <- data.frame(parcelas.cobtot.conti)
> is.data.frame(a)
[1] TRUE
>
> dim(a)
[1] 1600 3
Why a does not have the same dimensions than
parcelas.cobtot.conti?
I've tested with caith and the behaviour there

[OT] correspondence analysis w/ non-mutually-exclusive ca tegories
Andy,
Take a look at Greenacre, Theory and Applications of Correspondence
Analysis. He has many example of dealing with all sorts of data.
Basically, the technique is relevant for 2-way tables -- MCA is an
extenstion. It is not clear in your example whether CA is really
appropriate -- you want to make an observation (if at all possible) fall in
one cell, treating the others layers as

[OT] correspondence analysis w/ non-mutually-exclusive categories
Greetings, again. This is not strictly an R question, so please feel free
to ignore it if you like.
My question is about the substance of correspondence
analysis. Specifically, is it appropriate to use ca on a matrix of values
such that the columns and/or rows are not mutually exclusive? To be more
detailed:
- The standard use of ca is illustrated in the example of corresp() (from
MASS):

Unreadable labels
Playing around with examples from MASS4, I found a font problem in the
mosaicplot in R-2.3.0. It doesn't happen in other plots. Running this
example from MASS4, page 326...
library(MASS)
caith1 <- as.matrix(caith)
names(dimnames(caith1)) <- c("eyes", "hair")
mosaicplot(caith1, color = TRUE)
...I get an image as attached. The column and row labels are unreadable.

Plot with different x axis
dear,
I am trying to plot a standard plot, but I want the x axis to be 1,2,4,8,16 with equal intervals between them on plot.
I will appreciate some help.
Thank you,

Morlet wavelet analysis
...function "wavelet" from dplR package.
library(dplR)
D2<-wavelet(d1,Dt=1)
But the wavelets from two tests are very different. What is the reason??
Thank you,

Plot contour inside a polygon
...inside UK area, so that no contours are plotted over the sea. I was wondering if anyone can help me with this task and if I can get any suggestions how to do that.

'Apparently' trouble with name spaces and Sweave...
Ben Bolstad experienced something odd while running R CMD check over
a package of ours using r-devel (yesterday's fresh).
He tracked down the problem to a vignette calling 'library(MASS)'.
Please kindly ignore if this is a known (and temporary) issue.
