Hi,
I'm a bit confused by masking. Thought I understood, but today makes me
wonder.
x=0:9
y=0:9
sm=data.frame(x=4:8,y=9:13)
attach(sm)
x
detach(sm)
The code produces this message:
> attach(sm)
The following object is masked _by_ .GlobalEnv:
x, y

Hi
The outline for France from that database is a little bit pesky because
it consists of multiple segments that travel in different directions
around the French border. Here is some (possibly jetlagged) code that
puts the segments all in the same direction and produces a nicer result ...

I like very much the solution proposed by Paul Murrell to mask the ocean
(in fact, all that is not the country displayed) in a plot. It works
pretty well for Australia. However, when I try to apply the same code
for France, it fails. I search for the reason but I can't find. Here is
the code fo
Many thanks, this works beautifully.

Hi
There are a couple of problems:
1.
Your 'outline' is much bigger than it needs to be. For example, the
following produces just Australia ...
outline <- map("worldHires", regions="Australia", exact=TRUE,
plot=FALSE) # returns a list of x/y coords
2.
The outline you get stil
Hi R-help
I am trying to mask the ocean from an image plot I have made.
Here is some example code:
library(mapdata)
image(x=110:155, y =-40:-10, z = outer(1:45, 1:30, "+"),
xlab = "lon", ylab = "lat")
outline <- map("worldHires", plot=FALSE) # returns a list of x/y coords
xrange <- ra

I am using the function permutations from the package *gregmisc*. However, I
am also making use of the package *e1071*, which also contains a function
called permutations. I want to use the function permutations from the *
gregmisc* package, however, the other package is masking this function. This
I am using getYahooData from TTR to get daily data. When i do it standalone,
it is fine. It also works fine inside my code. However, when i run code
inside mtrace(), i always get the following error:
Error in xts(cbind(adj[[1]], adj[[2]]), index(obj)):
