Dear all;
This must have a rather simple answer but haven't been able to figure it
out: I have a data frame with say 2 groups (group 1 & 2). I want to select
from group 1 say "n" rows and calculate the mean; then select "m" rows from
group 2 and calculate the mean as well. So far I've been using
Dear R user;
Consider the following toy example
A - data.frame(ID1 = c(1,2,3,1,2,3,1,2,3), ID2 =
c(a,b,c,d,e,f,g,h,i), stringsAsFactors = FALSE)
B - sample(a$ID2, 6, replace = TRUE)
Lets say B is = a, a, a, h, b, e
I want to extract from A the rows where ID2 == B. If I use
AA - A[A$ID2 %in% B
Dear R community;
I'm kind of stuck with the following situation and would appreciate any
hint. Let's assume I have the following data frame:
dat - data.frame(ID = c(rep(01,18), rep(02,16)), USE = c(c(001,004,
005,007,001,004,005,007,012,001,004,005,007,001,004,
Dear R users;
Consider the following toy example:
a - matrix(c(2,3,4,NA,NA,5,8,NA,8,NA), 5, 2)
b - cbind(a,apply(a, 1, diff, na.rm = TRUE))
What I would like be able to get is:
c - matrix(c(2,3,4,NA,NA,5,8,NA,8,NA,3,5,-4,8,NA), 5, 3)
i.e., for each row if both values (column 1 and 2) are NA
Dear R-users;
I'm working with a a dataset that was previously used to fit a
nonlinear model of the form:
Y ~ a * (1 + b * log(1 - c * X^d))
The parameters published elsewhere are:
a = 1.758863, b = .217217, c = .99031, and d = .054589
However, there is no way I can replicate this result.
Perhaps you can try the examples given in
http://www.jstatsoft.org/v18/i02 for getting a better idea about how
the NIPALS algorithm works. BTW, yes,it looks like a homework question
specially when your user name is zz dd void1...@gmail.com so you
can't be recognized.

I'm tring to find a way to plot a solid of revolution in R, say
