Having some Trouble Data Structures
Hi All,
I'm trying to run a simulation of host-pathogen evolution based around individuals.
What I need to have is a dataframe or table of some description - describing all the individuals of a pathogen population (so far I've implemented this as a matrix):
ID No_of_Effectors Effectors (Sequences)
[1,] 0001 3 ## 3

Removal of columns from matrix where all values of the column are identical.
Hi all,
I'd like to write a piece of code which will remove columns from a matrix, if the column contains only one value, say every value in the column is a "3":
Matrix <- matrix(NA, nrow=5, ncol=4)
Matrix[,1] <- c(1,2,3,4,5)
Matrix[,2] <- c(3,3,3,3,3)
Matrix[,3] <- c(5,4,3,2,1)
Matrix[,4] <- c(5,1,4,3,2)
[,1] [,2] [,3] [,4]
[1,] 1 3 5 5
[2,] 2

Pairwise Comparrisons
Dear all,
I''m trying to write a function, that will take as an argument, some aligned genome sequences, and using a sliding window, do pairwise comparisons of sequence similarity. Coding the sliding window I think I can manage but what I''m trying to get to grips with is getting it so as every pairwise comparison is made, no matter how many genomes are added, from 3 to N.
So if

Extract cell of many values from dataframe cells and sample from them.
Hi,
First my apologies for a non-working piece of code in a previous submission, I have corrected this error.
I'm doing is individual based modelling of a pathogen and it's host. The way I've thought of doing this is with two dataframes, one of the pathogen and it's genes and effector genes, and one of the host and it's resistance genes. During the simulation, these things

function call from another r file
How to call a function from another r file ?
Anyone can help me .
Having a function named like fun1 which is saved in r file file1.r
and i have another r file like file2.r, and i need to call the fun1 (which
is in file1) within file2.
Thank you

Stuck trying to modify a function
Hi,
I have the following data:
Path_Number <- 5
ID.Path <- c(1:Path_Number) # Make vector of ID's.
No_of_X <- sample(50:550, length(ID.Path), replace=TRUE) #
X <- split(sample(1:10000, sum(No_of_X), replace=TRUE), rep(ID.Path, No_of_X))
Y <- lapply(X,function(x) sample(x, round(runif(1, min=10, max=50))))
X and Y are both lists, and I've made the following function to

Code works, but not as function.
Hi,
I have some values in a list format generated by the following:
Path_Number <- 0010
ID.Path <- formatC(0001:Path_Number, width=4, flag=0) # Make vector of ID's.
No_of_Effectors <- sample(1:550, length(ID.Path), replace=TRUE) # Define Number of Effectors each individual gets.
Effectors <- split(sample(1:10000, sum(No_of_Effectors), replace=TRUE), rep(ID.Path, No_of_Effectors))

While loop working with TRUE/FALSE?
Hi R users,
is there any possibilty that a while loop is working like that:
z <- c(0,1,2,3,4,5,6,7,8,9)
r <- 7
while(w == T) {
for ( i in 1:10 ){
w <- r == z[i]
print(w)
}
}
The loop should stop if w == TRUE
best regards

cache most-recent dispatch
Hi,
S4 method dispatch can be very slow. Would it be reasonable to cache the
most
recent dispatch, anticipating the next invocation will be on the same
type? This
would be very helpful in loops.

sapply(x, paste, collapse="+")
fun1 <- function(x) {
paste <- selectMethod(paste, class(x[[1]]))

ifelse(is.na), with function inside
Hi,
I have a vector a=c(NA, 3, 4, 4, NA, NA, 3) and I would like to use is.na(a)
function to get a vector like this:
wy=(1,2,2,2,1,1,2) - you know, this vector create 1 or 2 depends on value in
vector "a"
This is my short code but something is wrong and I don't know what...

Extracting overdispersion estimates from lmer amd glm objects
Dear list,
I am needing to extract the estimate of overdispersion (deviance / residual degrees of freedom or c-hat) from multiple model objects - so they can then be used to compare the extent of overdispersion among alternative models as well as calculate qausi-AIC values. I have been unable to do this, despite consulting a number of manuals and searching the R-help. I am imaging that in

R-beta: Dec alpha
R ran find on our Sun until it was stolen. I have now set up R on one of
our Dec Alphas OSF1 V4.0 386. R-0.49 configures builds and runs fine
except that the glm command crashes R. R-0.60.1 configures builds and
runs until a cis entered. I think the problem is the floating point
conventions but before I get in over my head a question
Has anyone used glm successfully on Alphas OSF1 V4.0 386?

pass "..." to multiple sub-functions
Dear list,
I know I have seen this discussed before but I haven't been successful
in searching for "ellipsis", "dots", "..." in the archives. I would
like to filter "..." arguments according to their name, and dispatch
them to two sub-functions, say fun1 and fun2. I looked at lm() but it
seemed more complicated than I need as it modifies the calling

how to eliminate an element of a list
Hi,
I want to eliminate an element of a list:
list <- seq(1,5,1)
s <- sample(list,1)
lets say s=3
Now I want to remove 3 from the list: list2 = {1,2,4,5}
Can someone give me a tip?

Problem with Variance Components (and general glmm confusion)
Dear list,
I am having some problems with extracting Variance Components from a random-effects model:
I am running a simple random-effects model using lme:
model<-lme(y~1,random=~1|groupA/groupB)
which returns the output for the StdDev of the Random effects, and model AIC etc as expected.
Until yesterday I was using R v. 2.0, and had no problem in calling the variance components of the
