I'm pretty sure the problem is with your data frame. Maybe if you share the
result of
dput(training[1:10, ])
# (make sure to include
Gab,
Make sure you have variables for each training.
training <- data.frame(Training_2006, AST_L1B_1, AST_L1B_2, AST_L1B_3N)
If you can't do that, then you don't have as many training observations
than you have predictive informations. Make sure to create a line for each
set of predictive pixels
Uday, maybe you could have a look at the raster package.

Supakorn,
Try:

I'm looking for a palette that would maximize the discrepancy with
neighbouring elements.
I have a raster image of objects tagged with integers. I'd like to
highlight the different objects by using a palette that would maximize this
difference with neighbours as close numbers tend to be neighbours
Salut Julien,
t1 <- table(data1$Id01)
t2 <- table(data2$Id02)
# compute difference between the two tables
diff <- t1-t2
# create your data frame from data2
res <- data2
names(res)[1] <- "Id01"
lsAdd <- rep(attributes(diff)$dimnames[[1]],diff)
defVal <- NA
rbind(res,data.frame(Id01 =lsAdd, Are
Maybe if you could send that path via the arguments, you could get them back
using commandArgs().
Then you can setwd() and paste() to generate paths.

When using mix() form the mixdist package, I sometimes get NA's and NaN's in
the Standard Errors estimates. I've understood from the code that mix() it
is using Non-linear minimization (nlm) to estimate thoses errors, but I
can't understand how to interpret theses results. Does any one have a (web

You could also make some algebra. e.g. :
?rweibull
gives the formula of the mean and of the cumulative distribution function in
the Details section. So using your known parameters (i.e. mean=30 and
p(10)=.10, i.e. cumulative function(10) =.90), I think it is sufficient to
determine the exact val
Hi,
With two data sets, one complete and another one partial, I would like to
merge them and keep the unmatched lines. The problem is that merge() dosen't
keep the unmatched lines. Is there another function that I could use to
merge the data frames.
Example:
completedf <- expand.grid(alpha=lett
Thanks Hadley,
Is it the solution you would recommend ?
rgb(pal.cr((0:40)/40), maxColorValue=255)

I try to use ColorRamp as ColorRampPalette (i.e. with the same gradient), but
it seems there is a nuance that I've missed.
pal.crp<-colorRampPalette( c("blue", "white", "red"), space = "rgb")
plot(rep(0,40),pch=16,col=pal.crp(40))
# is great
But, using the same gradient with colorRamp is giving

Even if it's not so elegant, I will bind it in a function, so I don't have to
bother with that anymore. I think there should be a simple function in R to
initialize an empty data frame. From what I've read, it is a recurrent
question on that list.
