[R] Formatting output of plotKML

Hello, I previously submitted the below query to r-sig-geo, but have had no response. Before I start bothering individual maintainers, I wonder if anyone on this list has any experience with the package and (or!) can diagnose my problems? Thanks, Calum Hello, I am having a little trouble with

Re: [R] help ANN

I would like to create an artificial neural network with R but I don't know its parameters jet (number of layers, number of neurons,...). I downloaded the package ANN and I use the function ANNGA, but I'm afraid I haven't really created a neural network. In fact, at the end of the process I

[R] Lasso function that can handle NA values

Hi everyone, I have a large dataset with missing values. I tried using glmnet, but it seems that it cannot handle NA values in the design matrix. I also tried lars, but I get an error too. Does anyone know of any package for computing the lasso solution which handles NA values?

Re: [R] Lasso function that can handle NA values

?na.omit ?? But it is certainly true that omitting missing values first and analyzing the remaining data can: 1. Leave you with no data to analyze 2. Result in biased and misleading conclusions if the missingness mechanism is related to the covariates. In general, handling data with missing

Hi, I used that because 10% of the values in the data were already NA. You are right.  Sorry, ?match() is unnecessary.  I was trying another solution with match() which didn't work out and forgot to check whether it was adequate or not. set.seed(49)

I see your desired output has rather fewer data than the input data frame. Instead of making us pore over a bunch of numbers, can you explain exactly what filtering you wish to do to get the specific subset of {male/female} {alcohol/caffeine} you're trying to get? BHM wrote Hi, This is

An essentially identical approach that may be a tad clearer -- but requires additional space -- first creates a logical vector for the locations of the NA's in the unlisted data.frame. Further NA positions are randomly added and then the augmented vector is used as a logical matrix to index where
