For Loop performance
Hello,
Newbie question and hope you can help .
I have two vector V1 and V2, where length(V2) = length of (V1) * 2;
length(V1) ~ 16,000.
For each member in V1, I need to compare 2 element of V2 for equality
i.e.
for (I in 1:length (V1)) {
if ( v2[i] == v1[i] & v2[i+1]==v1[i] ){
statement_1
statement_2
.
}
}...

binary order combinations
Dear all!
I have a vector of names
names<-("V1", "V2", "V3",....., "V15")
I could create all possible combinations of these names (of all
lengths) using R:
combos<-lapply(1:15,function(x)
{combn(names,x)
})
I get a list with all possible combinations of elements of 'names'
that looks like this (j...

pass-by-reference
I'm working with a large object that I want to modify slightly in a function.
Pass-by-reference would make a lot of sense, but I don't know how to do it.
I've searched this archive and thought that I can do something like
f <- function(x) {
v1 <- list(a=x,b=3)
g(x)
v1
}
g <- function(x) {
frame <- parent.frame()
assign("v1",list(a=x,b=x),frame)
}
f(4)
returns list(a=4,b=4)
but what if I wanted to make v1[[1]] = v1[[1]] + v1[[2]] without creating a
copy of v1?
f2 <- function(x) {
v1 <- list(a=x,b=3)...

Creat new column based on condition
Hi,
How can I accomplish this task in R?
V1
10
20
30
10
10
20
Create a new column V2 such that:
If V1 = 10 then V2 = 4
If V1 = 20 then V2 = 6
V1 = 30 then V2 = 10
So the O/P looks like this
V1 V2
10 4
20 6
30 10
10 4
10 4
20 6
Thanks in advance...

Unexpected behavior of predict and interval="confidence"
Based on some recent r-help discussions, I have been trying out
plotting confidence intervals using predict and matplot. Matplot
appeared to not be plotting the linear regression when using the
default column names generated by read.table (V1, V2, etc). On
further inspection, the error seemed to be with predict and vector
names (V1, V2) rather than with matplot. I was using some textbook
data sets that were read with read.table, so my data.frame columns
were named by default. The problem seems to be related to the name of
the...

data frames; matching/merging
...one. But I'm convinced there must be a faster (and probably more
elegant) way to accomplish what I'm looking to do (perhaps using the
"merge" function?). I figured somebody out there might've already
figured this out:
I have a dataframe with two columns (let's call them V1 and V2). All
rows are unique, although column V1 has several redundant entries.
Ex:
V1 V2
1 a 3
2 a 2
3 b 9
4 c 4
5 a 7
6 b 11
What I'd like is to return a dataframe cut down to have only unique

How to test the difference between paired correlations?

package that does that
[https://search.r-project.org/CRAN/refmans/DescTools/html/FisherZ.html].
Yet, I do not understand how to process the data. Shall I pass the raw
data or the correlations directly?
I have made the following working example:

create new column in a DF according to values from another column
Hi everyone,
I have a small problem in my R-code.
Imagine this DF for example:
DF <- data.frame(number=c(1,4,7,3,11,16,14,17,20,19),data=c(1:10))
I would like to add a new column "Station" in this DF. This new column must
be automatically filled with: "V1" or "V2" or "V3".
The choice must be done on the numbers (1st column).
For example, I would like to have "V1" in the column "Station" in the rows
where the numbers of the 1st column are: 1,7,11,16 ; then I would like to
have "V2" in the rows w...

V2b <- c (37, NA, 15, NA, NA, NA, 90, NA, 161, NA)
