Dear list, I am running a lmer model and have a question. When ever i put a factor (Mag) in my model it lowers the AIC of the model, however the intercept is the only value with significant p-value. I have looked at the coefficients and the standard error and something jumps out at me. Estimate Std. Error z value Pr(>|z|) (Intercept) -1.35778 0.30917 -4.392 1.12e-05 ***

Dear users, I am attempting to plot an ols() call from the Design package, by following the procedure explained by Harald Baayen in his 2008 book 'Analyzing linguistic data. A practical introduction to statistics using R', page 175-181. I've attached my data to this e-mail (I hope it's small enough that that's ok). First I paste all the commands I ran, followed by the

Hi R-users, I have a simple question for R heavy users. If I have a data frame like this dfr <- data.frame(id=1:16, categ=rep(LETTERS[1:4], 4), var3=c(8,7,6,6,5,4,5,4,3,4,3,2,3,2,1,1)) dfr <- dfr[order(dfr$categ),] and I want to score values or points in variable named "var3" following this kind of logic: 1. the highest value of var3 within category (variable named

Good Morning, I am trying to create a new column of character strings based on the first two letters in a string in another column. I believe that I need to use some combination of ifelse and grep but I am not totally sure how to combine them. I am not totally sure why the command below isn't working. Obviously it isn't finding anything that matches my criteria but I am not sure why. Any

I have a question regarding robust nonlinear regression with nlrob. I would like to place lower bounds on the parameters, but when I call nlrob with limits it returns the following error: "Error in psi(resid/Scale, ...) : unused argument(s) (lower = list(Asym = 1, mid = 1, scal = 1))" After consulting the documentation I noticed that upper and lower are not listed as parameter in

Colleagues, I am analyzing data collected during oceanographic cruises. We have conducted many cruises over the last decade. On each cruise we visit ~50 stations. At each station (termed EventNum)we lower an instrument that measures depth, temperature, salinity and oxygen every few seconds as it is lowered through the water. Data from all EventNums on all cruises are stacked, generating a data

I have a data frame containing children, with variables 'year' = birth year, and 'm.id' = mother's id number. Let's assume that all the births of each mother is represented in the data frame. Now I want to create a subset of this data frame containing all children, whose mother's first birth was in the year 1816 or later. This seems to work: mid <-

Can anyone tell me how to calculate a mid-p value for a chi-squared test in R? Many thanks, Andrew Wilson

I'm having some confusing problems transferring approximately 16GB, in about 541,000 individual files. What is happening is that I am starting with a blank destination directory on a gentoo system running samba 3.0.1, and pulling from one of two windows systems. The problems come in that each time I use rsync (version 2.5.7) over samba to keep the data on the gentoo system's side in sync

Hi I have two irregular time series, which are of different lengths and being and end at different times. For the common subset of time that they both span, they should have the same values, but the values may occur at slightly different time intervals. I am trying to "line up" the identical values and reconcile them. I have merged the two series into a zoo object which looks

Hello, I created a simple histogram with: myHist<-hist(myData) the object myHist now has two arrays (among the others): myHist$mids myHist$counts Since myHist$counts contains some "0", and I want to calculate the linear fit among myHist$mids and log(myHist$counts), I want remove the elements of both arrays where these "0" occurs. which are the possible solutions to this problem? (I'd like to avoid ge...

Hello I would like to pass a model formula as an argument to the with.mids function from the mice package. The with.mids functon fits models to multiply imputed data sets. Here's a simple example library(mice) #Create multiple imputations on the nhanes data contained in the mice package. imp <- mice(nahnes) #Fitting a linear model with each imputed data set...

I am trying to replicate the first example from stepAIC from the MASS package with my own dataset but am running into error. If someone can point where I have gone wrong, I would appreciate it very much. Here is an example : set.seed(1) df <- data.frame( x1=rnorm(1000), x2=rnorm(1000), x3=rnorm(1000) ) df$y <- 0.5*df$x1 + rnorm(1000, mean=8, sd=0.5) # pairs(df); head(df) lo <-

I'm trying to run e2fsck on a ~6TB filesystem which is about 90% full. We're doing backup to disk to this filesystem, and have a number of hard links (link counts up to 90). strace shows: write(1, "Pass 2: Checking ", 17) = 17 write(1, "directory", 9) = 9 write(1, " structure\n", 11) = 11 mmap(NULL, 91574272,

I am streaming a FLAC OGG stream to an ICEcast server (a continuous/endless stream) using the standard FLAC command-line encoder (capturing STDOUT). It seems, that with FLAC streams the song title (meta data) updates do not work. Also the ICEcast admin web interface isn’t working for FLAC; while it is working for MP3, AAC as well as OGG streams. I.e. when sending a continuous FLAC stream to

Hi all! I've just gotten into the FLAC world, and have read most of the documentation. I have a question: Mike Wren's frontend, upon looking at the DOS command line it automatically generates, uses the "-m" command. This is for "mid-side coding for each frame". What is this? Specifically, is this like the mid-side recording technique? If so, that means the
