to implement this in R?
I wouldn't have been here seeking for help if I had that "deep"
understanding of the issue under question Rolf!

Dear R users,
I wanted to test if there is significant difference between
probabilities of the same event calculated in different ways. I am
aware about the prop.test() which does the comparison between two
proportions given the number of successes and sample sizes. But in my
case the only values
Dear all,
I have installed necessary packages such as ncdf4 and RNetCDF. But
still my machine can't read netcdf files into R. Below are the file
formats and the respective errors:

Dear R users,
For a time series, say y:
y-cumsum(rnorm(100)) # I used ur.df function (urca package) to test
for unit root with/without a drift as follows:
test-ur.df(y,lags=3,type=drift) # this works for the artificial
data here, but when I apply the same function to my very big data, it
comes
I have a 3-dimentional data set with dimensions longitude,
latitude, and time. Unfortunately, when I look at the range of
values in the data set, I noticed some very extremely large(positive
and negative) values which are unexpected to be there. So I wanted to
point-out the location (lon, lat and
right now) argument to which (). I have used it for 2-dim arrays and never
for higher dimensions. But try it out by setting the argument to TRUE.

Dear R users
I want to paint parts of a polygon with different colours conditional
to values of the variable.
Example:
f-seq(1,33)
g-sin(f)
i-rep(0,33)
ff-c(f,rev(f))
gg-c(g,rev(i))
plot(ff,gg,type=n)
polygon(ff,gg,col=2) # but I wanted to plot areas below and above the
x-axis with different
7 matches
