Hi, Could someone tell me if this is the correct model syntax for the following dataset: lme(height~treatment+genotype+treatment*genotype,drought,random=~genotyp e) The dataset has two factors: one fixed - treatment, and one random - genotype. I need to test the effect of both factors to identify their significance. There are multiple (but not equal) replicates at each level of genotype (the

hi i try to use arima and holtwinter to predict drought from 1895-2006 but i cannot read whole period of time and i try to do the exponent fitting, but it comes out as the coordinate x-y error i send the source code and data to take a look if anyone can help me, i am really new in R thank u so much jam

Dear R-help community, I have looked on the R search site and archives but cannot find mention of a way of interpolating a gaussian distribution of data to a standard 2.5 degree grid. I have two global dataset and I need to correlate - unfortunately one is a 2.5 degree grid dim[longitude=144,latitude=72] and one is gaussian dim[longitude=192,latitude=94]. I would rally appreciate hearing

Dear R-Help friends, I am unable to get the latest version of R (2.4.1) to compile on my solaris 10 system - has anybody else experienced this problem and are you able to offer me any advice? I appreciate your time, many thanks, Jenny Barnes Here are my CURRENT specifications: platform sparc-sun-solaris2.10 arch sparc os solaris2.10

Dear R-help, Which random number generator function would you recommend for simply picking 15 random numbers from the sequence 0-42? I want to use replacement (so that the same number could potentially be picked more than once). I have read the R-help archives and the statistics and computing book on modern Applied statistics with S but the advice seems to be for much form complicated

Hey all, I''m back. Some of you are probably thinking that is the longest weeks vacation on record. Well, I''d like to take this opportunity to apologise for my absence and offer a brief explanation. When I got back to Australia I naturally went home to visit my parents, only to find that they have been hit really hard by the drought. They didn''t really tell me just how

Hi everybody, My name is Jackson and come here ask for a help to organize data. I really need help from you. I have several data sets to organize. I have to summarize precipitation data collected in different days and months in only one table. However, those data are disperse in days and times. Those rainy days have a more observations than drought ones. Below you can find a hypothetical

Hi R user, Would you mind to help me to find the range with stochastic events? For example, daT<-structure(list(sn = 1:14, growthrate = c(0.5, 0.6, 0.7, 0.99, 0.1, 0.3, 0.4, 0.5, 0.5, 0.2, 0.1, 0.4, 0.3, 0.43)), .Names = c("sn", "growthrate"), class = "data.frame", row.names = c(NA, -14L)) I want to find the ranges of growth rate of the above data using Mote

Dear all, I'm trying to make an R code for the drought severity index (DSI) developed by Philips and McGregor (1998). You can refer to the description of the algorithm on page 19 from http://dissertations.port.ac.uk/229/01/MaloneS.pdf The code is given in Excel as the following and can be found on page 60 from the same link. C7 = IF(C6<0,IF(@SUM(A6:A1)<0,C6+A6,"0"),

Dear R-Help community, I am trying to overlay a single contour line over a correlation plot using levelplot in the lattice package. These are the two arrays: 1) a correlation plot over Africa - so each grid square is a different colour dependent on correlation - this is in an array: result_cor with dim[465,465] 2) a single contour line from a ***different data source*** - this is from data

type count 0 20 1 15 0 10 1 35 0 28 I would like to create two vectors from the data above. For example, type1=c(15, 35) and type0 = c(20, 10, 28). Can any one help Raphael

Dear R-community, I am looking for some simple advice - I have a matrix (therefore 2 dimensional) of global temperature. Having read R-help I think that when I ask R to image() or levelplot() my matrix will it actually appear upside down - I think I therefore need to use the line: > levelplot(temperature.matrix[,ncol(output.temp):1], ........) to get it looking like it was on the globe due

Dear R-help, I have a loop, which is set to take about 26 hours to run at the rate it's going - this is ridiculous and I really need your help to find a more efficient way of loading up my array gpcc.array: #My data is stored in a table format with all the data in one long column #running though every longitute, for every latitude, for every year. The #original data is sotred as

Dear R-help community, I have 2 different arrays of precipitation data each of the same dimensions of [longitude, latitude, time] dim=[30,32,43], called array1 and array2. I need to correlate them. This is the code I used to get one overall correlation value for the whole of the area of interest: > result <- cor(array1,array2,use="complete.obs") > result This give me a

Dear R-Help, I am trying to find a function that will give me the significance of the correlation of 2 variables (in the same dimension arrays) correcting for serial autocorrelation. How can I view the function cor.test's code? I would like to know a lot more detail about the function than written in the documentation at http://finzi.psych.upenn.edu/R/library/stats/html/cor.test.html to

My data set is large with the log2 fold change for over 6oo genes across 4 treatments. My csv file is formatted as such: Gene Drought Ozone Temp1 Temp2 Glyma0041s00260

This is pretty badly mangled (please don't post in html), but ?aggregate is probably what you want.

Dear R-help community I am trying to write an R object (data.out) to a file in order to re-access it later and not have to re-load up the array with data every time. Here is the form of data.out > data.out <- list(lats=seq(88.542, -88.542, length=94), lons=seq(0, 360-1.875, length=192), date=vector(length=nyr*12), data=array(NA, c(nyr*12, 94*192)) ) I tried >
