I am having trouble install rgdal. I am using
Red Hat Enterprise Linux Server release 5.5 (Tikanga)
and having the problem shown below when I try to install
rgdal.
I have previously installed rgdal including building gdal
from source so I am not new to this but have not previouly
installed it on t

Try this:
library(help = maps)
# show polygon names in order
map("state", fill = TRUE, plot = FALSE, names = TRUE)
# make first polygon have color 1, second 2, etc.
map("state", fill = TRUE, col = 1:63)

I am getting this message when I try to install rgdal in R:

the proj-nad and proj-epsg RPMs on systems using RPMs,

Use this:

See draw.circle and maybe draw.arc in the plotrix package.

They are using different coefficient parameterizations but the models
are otherwise
the same. For example, they give the same fitted values:

[1] TRUE

Thanks. In my case the region of interest is no larger
than a city block so I fall into your simpler case.

ust a regression I guess I can ditch surf.ls
and use lm in which case I can get the coefficients
explicitly and figure it out from there.

How can we plot lines on the graph to show the
principal directions/axes of the elliptical contours
and how do we get them?
Thanks.

I am currently doing the following to draw circles at the
indicated distances from the center. The center is given
by utm coordinates: utm.e, utm.n . It does work:
class(im2) # "SpatialGridDataFrame"
image(im2, "ind", col = col$ct)
library(plotrix)
dd <- c(25, 50, 100, 150)
for(i in 1:4) draw.ci
Not sure if this will become an issue but in case I need
it to justify my toolset does anyone have a list of
recognizable organizations that use R for geographic
processing?
Thanks.

All my points are in zone 18. How would I accomplish the same
thing using R?
Thanks.
