creating a list of lists
Hello, I'm trying to create a series of randomForest objects, basically in a loop like this: forests <- list(); for (level in 1:10) { # do some other things here # create a random forest forest <- randomForest( x = x.level, y = z.level, ntree = trees ); forests <- c(forests, forest); } But instead of creating...

package metafor: error when setting 'col' and 'at' for a forest plot
I am using metafor to create forest plots. This code gives me the expected plot (setting x axis tick marks): forest(forest$OR, ci.lb=forest$Low, ci.ub=forest$High, at=log(c(.05, .25, 1, 10)), slab=forest$SNP, atransf=exp) As does this (setting colors): forest(forest$OR, ci.lb=forest$Low, ci.ub=forest$High, col=c(1,2,3), slab=for...

Re-evaluating the tree in the random forest
Dear mailinglist members, I was wondering if there was a way to re-evaluate the instances of a tree (in the forest) again after I have manually changed a splitpoint (or split variable) of a decision node. Here's an illustration: library("randomForest") forest.rf <- randomForest(formula = Species ~ ., data = iris, do.trace = TRUE, ntree = 3, mtry = 2, norm.votes = FALSE) # I am going to chang...

To be more clear, my data set contains 1500 rows, and I am growing 500 trees in Random Forest Is it possible to sample only 500 rows of data from the data set and use it for different...

Clustering nested data
Hi all, I am interested in performing a cluster analysis on ecological data from forests in Pennsylvania. I would like to develop definitions for forest types (red maple forests, upland oak forests, etc.(AH AR in attached table)) based on measured attributes in each forest type. To do this, I would like to 'draw clusters' around forest types based on information from various...

forest (meta) editing text
OK - I've been doing some work on getting a forest plot or two together for a sub-group analaysis. Thats the crucial thing - because its a sub-group analysis rather than a meta-analsysis and all the forest (meta) and forestplot (rmeta) instructions assume you are doing a meta-analysis. I found rmeta didn't play nicely for me so I'm using...

Is this always the case with random forests? Can someone please clarify this? I have given a simple example, first using logistic regression and then using random fore...

My forest plot is not fit to windows in R software
Dear Fahimeh It would help if you also told us what package you are using as there are several which perform forest plots. I assume it is meta. Your plot is cropped on three side as far as I can see. What parameters did you give to the call of the graphics device? What happens if you use a different graphics format like pdf? Then we may be able to see where the issue lies.

Annotate forest plot 'forest.rma()' for meta-analysis with metafor package
Dear R-experts, The forest.rma() function from the metafor package creates nice forest plots for presenting the results of a meta-analysis. These plots can be annotated for e.g. giving names to the columns. E.g. as in the documentation of the package: data(dat.bcg) ### meta-analysis of the log relative risks using a random...
