Here is one way of doing it:

Hello,
First please keep in mind I am not a programmer and know very little about R. I
am running the 64bit version of R on a Windows 8.1 machine. I am trying to run

There are two issues here:
1) Paths. Use Sys.which(wget) to see if the command is on your path.
I suspect it is not, and you need to set the path when running R in
the same way as is done for your shell. Compare the
Dear helpeRs,
let a - 1:10
let b - integer(0) first, then i will randomly write a integer differently
in the range(1,10) or NULL into b. for supposed 5 times.
then i want to get a[-b],that means i not want the values at index b.
if any time of 5 times generate a integer, it

I don't understand what you think it should actually return. As for why it
should behave the way it does now... hmmm, keep in mind that each
sub-expression needs to make sense as well.
Consider -integer(0)... applying the unary negation operator to a vector of
integers yields a new vector of

1) The paths are properly set...I only wonder if the spaces in the path to

As I understand it right, there is no possibility to give variables or

Just for example. x need a name. And the four values (1, 2, 3, 4)

It looks like a terminology issue. R has names for elements of a
vector and for rows and
columns of a matrix or data.frame, and more generally for all
dimensions of multi-dimensional array.
I think your next step is to read the introductory document.
Start with either of these (they are the same
No, you are wrong. Read the docs! -- start with An Introduction to R
which ships with R.
Please do not post further until after you have done your homework.

You can use 'factors' to assign labels to small integer values. E.g.,
x - c(1,2,3,4,3)
fx - factor(x, levels=1:5, labels=c(One,Two,Three,Four,Five))
table(fx)

You are separating the objects using commas, the correct should be semicolons.
Example:
xi1=matrix(data=rep(0.0,600),ncol=3);xi2=matrix(data=rep(0.0,600),ncol=3))

To do this, you will need to run train again and modify the index and
