Dear Melissa,
Normally, in evaluating a formula an R modeling function follows the
scoping rules in ?formula; that is,
"A formula object has an associated environment, and this environment
(rather than the parent environment) is used by model.frame to evaluate
variables that are not found in
John,
Thanks for your response. I agree that the definition of the data frame is
poor (in my defense it came directly from the demo code, but I should have
checked it more thoroughly). The good news is that your comments caused me to
take a closer look at where X was defined, and I found the
Dear Melissa,
It seems strange to me that your code would work on any platform (it
doesn't on my Mac) because the data frame you create shouldn't contain a
matrix named "X" but rather columns including those originating from X.
To illustrate:
> X <- matrix(1:12, 4, 3)
> colnames(X) <- c("a",
I am trying to replicate a semi-parametric analysis described in Harezlak,

Ah I see.
Thank you very much!

Got it. Thank you very much.

Yes, the Mercator projection unwraps the globe (360 degrees around)
while the poles are 180 degrees apart. It then stretches the result
into a rectangle. If you enter:
par("usr")
after drawing the world map you will see the proportions.

No need to apologise. I may by wrong as I did not dig into the map code and do
not use the package so I only guess. You could check how mar changes by

[1] 5.1 4.1 4.1 2.1
So
par("mar")
par(mar=c(2, 6, 5, 4))
par("mar")
m<-map('world', xlim = c(91, 142), ylim = c(25, 40), lwd
Hi Jim,
Thank you for the alternative. Absolutely will try it.
Can you explain a bit about "Maps draws an approximately 2x1 plot"?
Is it the size proportion 2 in x-axis and 1 in y-axis?

Hi Petr,
Thank you for pointing that out! Silly newbie here.
So, just want to make sure my mind,
using my example:
par(mar=c(2, 6, 5, 4))
m<-map('world', xlim = c(91, 142), ylim = c(25, 40),
lwd=1.5, col = "grey",border=NA, fill = T, bg="white")
box()
first, map use the first mar=c(2,6,5
10 matches
