I want to read all matrices into stoch.projection( ) {popbio}
Thanks for any suggestions. I could enter them all in the .txt document if I
can't read them from the Excel sheet.

NA in wilcox.test
...several NAs in the data which is all I can figure that is
non-numeric.
Any suggestions as to the problem? Is it a problem with having several
columns/sets of info for each individual?
Thanks for any help anyone can give (I've also used Arlequin and GDA but
want non-parametric tests)

My code is:
scirconv2 = read.csv("CaScSc070420_2.csv", na.strings="?")
CaScSc = scirconv2[1:250,3:21]
CaScCo = scirconv2[251:475,3:21]
ScCoMWU = wilcox.test(CaScSc, CaScCo, alternative = "two.sided", mu = 0.5,
paired = FALSE, exact = NULL, correct = TRUE,...

Popbio - can't find or load
Hello,
I'm in need of running a PVA and want to load {popbio}. However, I can't find
it. I can't see where or how to load it. I have added repositories and
changed the CRAN mirror site. I see {polynom} and {popgen} but no {popbio}
between.
What am I doing wrong?
Thanks,
Michelle

projection.matrix() {popbio} for more than one matrix
Hello,
I am trying to use the projection.matrix( ) function and am following the
example given. I have my data formatted very similar to the test.census
example.

Stress in multidimensional scaling
Hello,
We are trying to find a function to compute "stress" in our
multidimensional scaling analysis of a dissimilarity matrix. We've used
"dist()" to create the matrix and "cmdscale()" for the scaling. In order
to determine the number of dimensions we would like to plot stress vs.
dimensions. However, we cannot find a pre-made command. It seems that

cloud() 3D scatter plot
Hello,
I am creating a 3D scatter plot with the cloud function. I ask it to
group my rows by a "Treatment" column (there are 4 different groups). I
need to know which points in the plot correspond to which rows (which
treatment). By default it assigns pchs and cols to each group. When I
try to define the colors or point shapes it seems to use the first color
and pch for both the first

cloud() question
Hello,
I am trying to plot lines in 3 dimensions from a multiple linear model
to illustrate the interaction of two of the explanatory variables. I'm
trying to use the cloud function (though I'm open to a different
function if an easier one exists). I keep getting the error message:
Error in cloud(lmPeHa061201, data = PeHa061201, cex = 0.8, main =

Modify the plot from countCDFxt
Hello,
I am running the plot from countCDFxt (popbio). I would like to report the
y-axis as a percent instead of the log scale (e^01...). I can add an axis
with axis(2, 0:1, line =2) but I'm having trouble understanding how to assign
the tic marks (with 'at ='). I'd like to tell it to make tics with the
percent value (or decimal if that's my only option) at the equivalent of
