Multiple regression in R - unstandardised coefficients are a different sign to standardised coefficients, is this correct?
Hello, I have a statistical problem that I am using R for, but I am not making sense of the results. I am trying to use multiple regression to explore which variables (weather conditions) have the greater effect on a local atmospheric variable. The data is taken from a database that has 20391 data points (Z1). A simplified version of the data I'm looking at is given below, but I have a

Multiple count if style "queries"
Dear List, I am looking to calculate two things from my data frame and was after some advice. For the example below i want to know. 1. How many unique Orders/Families and Genera there are per eco-name 2. How many incidences are there for each Order/Family and Genus there are per eco-region I have 650 econame. I.e for Biak-Numfoor rain forests there are 2 orders, 2 families and two genera.

Hi Gabor and everybody; Thanks Gabor, with the alternative step you've told me the problem is resolved. Comparing the two procedures: Extract from the source 'character' data: > rain$ts[2039:2046] [1] "25/03/2000 22:00:00 UTC" "25/03/2000 23:00:00 UTC" [3] "26/03/2000 00:00:00 UTC" "26/03/2000 01:00:00 UTC" [5] "26/03/2000 02:00:00

Calculation of lags
Hi, If I have the follow situation: A dependent variable (i.e. number of insects) that is affected by an independent variable (i.e. rain). The problem is that the measure of rain affect the population in other moment. So there exit a lag between the rain and the number of insects. Exist in R any tool to find what is this lag? Explain better. Suppose that I have a linear relationship

help with regular expressions in R
I'm having trouble achieving the results I want using a regular expression. I want to eliminate all characters that fall within square brackets as well as the brackets themselves, returning an "". I'm not sure if it's R's use of double slash escapes or something else that is tripping me up. If I only use one slash I get 1: '\[' is an unrecognized escape in a

Need a help to plot bar for time series Rain data
Hey Guys, I am quite new to R, am trying to plot a bar plot for my monthly rainfall data from 1920 to 1990. For every year I have the data from January to December. I have created this code: data<-read.table("C://R//Data//Rain.txt", header=TRUE) data<-data[,2:13] Rdata<-data[1,] for(i in 2:79){Rdata<-c(Rdata,data[i,])} times<-ts(Rdata,start=1920,frequency=12)

Patch for water plugin to make time between rain-drops adjustable
Hello, I love the work that is being done with compiz! I have made a patch for water.c that makes the time between rain-drops adjustable using gconf. This way you can leave the plug-in running and just have pleasant drops every now and then instead of the rainstorm that is hard-coded in now (which is still fun now and then!). The gconf value is in ms (1/1000 of a second). Suggestions for

barplot - offsetting individual bars
Hello, I'm trying currently using barplot to summarize precipitation data. So far I've compiled total annual snow and rain accumulation in a table (attached). I've been successful at plotting it using the following code: fig=barplot(t(Annual_Precip_table), horiz=TRUE, space=0, col=c("grey70", "white"), axes=FALSE) . . The result is a stacked barplot with total

how to delete a parameter from list after running negative binomial error

I am having a bit of a problem when updating the model to remove parameters that I no do no autocorrelate with other variables (I have used a autocorrelation function for this). So my first model looks like this:

variance-covariance structure of random effects in lme
Dear R users, I have a question about the patterned variance-covariance structure for the random effects in linear mixed effect model. I am reading section 4.2.2 of "Mixed-Effects Models in S and S-Plus" by Jose Pinheiro and Douglas Bates. There is an example of defining a compound symmetry variance-covariance structure for the random effects in a split-plot experiment on varieties of
