Hi all, I have a data frame with names that in some cases have blank spaces:
TABLE$place
[1] La Blanqueada La Blanqueada La Blanqueada La Blanqueada La
Blanqueada
[6] La Blanqueada La Blanqueada Sargento Ponce Sargento Ponce La
Blanqueada
[11] La Blanqueada Sargento Ponce La Blanqueada
Ok, an extra blank space at the end was the problem. I missed it.
Cheers,

Dear list,
Reading a function I found this:
lm ( y ~ 1 )
I know that Y ~ -1 + A is a straight-line with no y-intercept; that is, a
fit forced through (0,0). But I never saw the first example. Any tip?
Thanks in advance!

Hi all, first thanks for a so useful package! I have a question about
gpagen. I understand that the resulting coordinates of this command are
in shape space, so for statistical analisys one must project them to
tangent space. But the command plotTangetSpace runs prcomp directly
over gpagen's
Dear List,
I can'f figure how to add point labels in the next plot (example from
?taxondive help page, from vegan package):
library(vegan)
data(dune)
data(dune.taxon)
taxdis - taxa2dist(dune.taxon, varstep=TRUE)
mod - taxondive(dune, taxdis)
plot(mod)
The points in this plot are diversity

Dear list,
I trying to make a wind rose plot whit the command oz.windrose, from plotrix
package. My data, a matrix of percentages with the rows representing speed
ranges and the columns indicating wind directions was generated
using bin.wind.records command from same package:
[,1] [,2]
Dear list, I'm trying to make a biplot, but instead of plotting the row
numbers for each observation, I'd like to plot a group factor.
Example:
prcomp(iris[,1:4]) - PCA
biplot(PCA) #this makes a nice biplot but with row names
Instead of row numbers I want to plot iris[,5], which is a factor.

Dear list.
I have three histograms and I want to add a vertical abline in a different
place in each plot. The next example will plot a vertical line at x=5.5 in
the three plots:
rnorm(100,5,3) - A
rnorm(100,7,3) - B
rnorm(100,4,1) - C
rep(c(A,B,C),each=100) - grp

Dear list, I want to plot several variables with splom and in the main
diagonal, instead of the variable names, I'd like to plot an histogram of
corresponding variables. Searching I did not find the correct syntax, only

Dear David, it works just perfect. Thanks a lot for the help

Dear list, I making some box-and-whisker plots in R with vertebrate
data. The x axis are species names that must be in italics. I tried
with the axis function but no luck, and it seems that affects both
axes.
Any tip?
Thanks a lot in Advance.

the correct aspect of the plot, however: font.main,
font.sub, font.lab or font.axis (from par()).

I'm confused on how is the right way to plot a discriminant analysis made by
lda function (MASS package).
(I had attached my data fro reproduction). When I plot a lda object :
X - read.table(data, header=T)
lda_analysis - lda(formula(X), data=X)
plot(lda_analysis)
#the above plot is completely
(-10,10)) and all the
points are superimposed. The only difference I found was the different x-
and y-axis when I drew them separately, i.e.
plot(z)
plot(predict(z)$x, col=palette()[predict(z)$class])

Hi,
I have a strange behavior of plot function when trying to plot a
discriminant analysis obtained by fda.
I'd attached the data for reproduction. I made the same analysis (linear
discriminant analysis) but using lda and fda (default args, using
polyreg). The resulting coefficients and trace
