step.gam
Dear R-users:
Im trying (using gam package) to develop a stepwise analysis. My gam
object contains five pedictor variables (a,b,c,d,e,f). I define the
step.gam:
step.gam(gamobject, scope=list("a"= ~s(a,4), "b"= ~s(b,4), "c"= ~s(c,4),
"d"= ~s(d,4), "e"= ~s(e,4), "f"= ~s(f,4)))
However, the result shows a formula containing the whole

Multidimensional Scaling (MDS) in R
...s each point in the plot has a
label.
This is what I did:
data <- read.table('c:/multivariate/mds/colour.txt',header=FALSE)
similarity <- as.dist(data)
distance <- 1-similarity
result.nmds <- nmds(distance)
plot(result.nmds)
(nmds and plot.nmds as defined at
labdsv.nr.usu.edu/splus_R/lab8/lab8.html; nmds simply calls isoMDS)
Colour.txt, containing the similaity matrix, reads as follows:
1.0 .86 .42 .42 .18 .06 .07 .04 .02 .07 .09 .12 .13 .16
.86 1.0 .50 .44 .22 .09 .07 .07 .02 .04 .07 .11 .13 .14

basic question
Dear R users,
Up to now, I only used precompiled packages. As I am working on vegetation
ecology, I would be interested in using a package not stored by CRAN called
labdsv_0.9-1.tar.gz and developped by Dave Roberts at the National Center
for Ecological Analysis and Synthesis (unfortunately I did not find any
corresponding .zip file).
Although I tried to follow the proposed guidelines to
