Please forgive the cross posting. I sent this to Medstats and have not received any response. I am looking for a good written explanation of components of variance (a.k.a variance components), in particular as they are used in genetic analyses. Does anyone have a suggestion? I am interested in books, articles and on-line material. I intent to give the material to some of my students none of whom

Hi all, I've been looking in R for an EM algorithm adjusted for multiple-locus haplotypes frequencies, but failed in 100%. Has anyone heard of anything of this kind in R? Thanks in advance, Marcin

Dear ALL: How I show the area under the normal curve for example for the following example: Assume X has N(100,15). How to show the area corresponding to the probability: P(90<X<110) With many thanks Abou ========================== AbouEl-Makarim Aboueissa, Ph.D. Assistant Professor of Statistics Department of Mathematics & Statistics University of Southern Maine 96

Un saludo: Estoy intentando con el comando "detach()" eliminar todos los archivos que durante la analíticas voy utilizando y "attached" al programa. El problema es que usando detach () no me borra todo lo adjuntado. No sé si estoy usando mal el comando o estoy usando un comando incorrecto que no es para esto. Gracias.

Gracias Carlos. Yo también he visto el ejemplo que te pone chatGPT, pero la salida que te da no soy capaz de interpretarla. Os paso las ordenes y las respuestas de R de la propuesta de chatGPT Ejemplo.aov<- aov(P~TRAT+CORTE+REP) > summary (Ejemplo.aov) Df Sum Sq Mean Sq F value Pr(>F) TRAT 6 0.0028 0.00046 0.777 0.590 CORTE 2 0.5022 0.25110 424.542 <2e-16

Buenas, En R, como en la mayoría del software estadístico, no se utiliza ningún nivel de confianza sino que lo que se calcula es el p-valor asociado al contraste. De forma que cuanto más cerca de 0 esté el p-valor "menos credibilidad le damos a la hipótesis nula". Dicho mejor, debemos rechazar la hipótesis nula si el p-valor está por debajo de nuestro nivel de confianza. Por ejemplo,

Hola a todos: Preguntar si alguien sabe si se puede conectar el Tinn-R con la versión 2.15 de "R" Yo lo he intentado y no lo consigo. si abro un script con el tinn-R no se me activan los botones para poder correr las lineas y que el resultado aparezca en la ventana de abajo de "R". Vamos como pasaba con la versión 2.14 Sin más un saludo a todos y gracias por

Hello, I have a data-frame in which one-column is a factor: > str(data); `data.frame': 194 obs. of 8 variables: $ Type : Factor w/ 3 levels "Nuclear-Rec..",..: 1 2 2 2 2 2 2 2 2 2 ... $ Locus : num 0.000571 0.004000 0.001429 0.004857 0.007429 ... And I'd like to make a boxplot of the data$Locus values, where each level of the factor gets its own

I am using dgc.genetics to perform TDT analysis on SNP data from a cohort of trios. I now have a file with about 6008 variables. The first few variables related to the pedigree data such as the pedigree ID the person ID etc. Thereafter each variable is a specific locus or marker. The variables are named by a pattern such as "Genotype.nnnnn" with nnnnn corresponding to a number which

#If I have two lists as follows a1<- array(1:6, dim=c(2,3)) a2<- array(7:12, dim=c(2,3)) l1<- list(a1,a2) a3<- array(1:4, dim=c(2,2)) a4<- array(5:8, dim=c(2,2)) l2<- list(a3,a4) #how can I create a new list with the mean across all arrays within the list, so all components are included?

Buenas tardes. Tengo un ensayo de dos factores (Variedad y dosis) Quisiera hacer anovas para cada una de las dos variedades que estoy evaluando. Lo puedo hacer cogiendo los datos primero de una variedad y luego de la otra. Pero creo que hay un comando "by variedad" que lo hace si necesidad de andar modificando el archivo de datos. Pero no sé dónde hay que colocarlo. Si alguno me puede

Hello, I am working with a matrix of multilocus genotypes for ~180 individual snail samples, with substantial missing data. I am trying to calculate the pairwise genetic distance between individuals using the stats package 'dist' function, using euclidean distance. I took a subset of this dataset (3 samples x 3 loci) to test how euclidean distance is calculated: 3x3 subset used

Hello R-help community, I have another question about filtering datasets. Please consider the following "toy" data matrix example, called "x" for simplicity. There are 20 different individuals ("ID"), with information about the alleles (A,T, G, C) at six different loci ("Locus1" - "Locus6") for each of these 20 individuals. At any single locus

Hi, I am trying to connect points on a graph that originate from *different columns of data*. For each sample I have minimum and maximum data points and I would like to draw a line connecting these in order to visualize the spread, as well as where each sample is in relation to the x-axis. So far I can generate the points, but the only lines I have been able to make join all the minimum values

Hi , is it possible to calculate ld-measures D, D', r and perhaps corresponding p-values with r IF THE PHASE IS KNOWN? The genetics - package provides the LD function only for ambigious phase. Thank you very much Bettina Kulle

Buenas tardes, Estamos intentando hacer un estudio sobre diversidad en gatos callejeros ('stray cats') de la base de datos 'nancycats' (librería 'adegenet') de R. Sin embargo, no entendemos muy bien los datos. ¿Alguien puede explicarnos a qué corresponde la variable respuesta? Entendemos que las filas son los 237 gatos (observaciones), y las columnas se corresponden con
