[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

[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 va

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) dat1[!is.na(dat1)][sample(seq(dat1[!is.na(da

Re: [R] Help with "Cast" Function

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

Re: [R] Adding NA values in random positions in a dataframe

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 t
