Hi,
I want to ue a randomisation test, to compare two sample means, for a
small set of data, I've looked at towt.permutation, perm.test and
permtest, as well as permTS(), which is the best one to use for such a
simple purpose? I know perm.test package isn't used anymore and coins
recommended,
Dear all, as per my understanding, outer() function is to facilitate
2-dimensional function evaluation, like to evaluate f(x,y) for different
values of x and y. However I have slightly modified version of that, where x
is a matrix with, say, 5 rows and 2 columns and y is a vector. Let take
Try this:
aperm(outer(x, y, fn1, y), c(3, 1, 2))[,,2]

Hi,
I tried it using abline but it is not showing any o/p(i.e no grids are
formed on map). I did following :
map('state','new york',proj='azequalarea',orient=c(42.5,-74.56,0))
abline(h=seq(41, 44, length=3))
abline(v=seq(-79, -76, length=3))
I also tried using map.grid() but in some cases it
Dear all, this is not a pure R question, but really about how to set up a
multinomial logistic regression model to do a multi-class classification. I
would really appreciate if any of you would give me some of your thoughts and
recommendation.
Let's say we have 3-class classification problem:
Dear list,
I am trying to replicate an econometrics study that was orginally done in
Stata. (Blanton and Blanton. 2009. A Sectoral Analysis of Human Rights and FDI:
Does Industry Type Matter? International Studies Quarterley 53 (2):469 - 493.)
The model I try to replicate is in Stata given
Thanks for the reply.
Yes, you are quite correct, but:

Dear Readers,
Sorry to bother you.
Have been try to read my data into R (something I have done in the past) but
having an error message with this one.
Any possible help please?
Thanks.

This is the error I am getting (please see bold):

Hello everyone!
I have a data frame of 136 variables with 270 observations. I would like to
create a new data frame such that each element of that data frame contains the
maximum value of the 6 prior lags of the initial data frame. So for example, if
my original data frame, A, were
A1=c(7.72,

Actually, Scott suggested ggplot2, which is available on CRAN:
http://cran.r-project.org/web/packages/ggplot2/index.html
Moreover, for the metafor package, you do not need (a,b,c,d) or standard
errors for the effect estimates.

Hi Henrique, thanks for your help. To be frank, I really could not
understand the process going on there. I was trying with following code:
x - matrix(1:10, nc = 2)
y - 20:22
fn1 - function(x1, x2, y) return (x1-x2+y)
outer(x, y, fn1, 1)
, , 1
[,1] [,2]
[1,] -18 -13
[2,] -17 -12
Listers,
I have a question regarding correlation matrices. It is fairly straight
forward to build a correlation matrix of an entire data frame. I simply use
the command cor(MyDataFrame). However, what I would like to do is construct
a smaller correlation matrix using just three of the variable
Have a look at

When you use a projection with map(), you subsequently have to transform your lat/long
coordinates to conform to the projection.
