Fit Gompertz' curve'
Hi,
I build a graph taking into account the times: 1,
2,4,6,8,10,12,15,18,21,24,28,32 and 48.
Be that the scale of the X axis does not look right. It
seems equidistant. (graph attached)
What changes have I to do in the following commands so that
the scale be correct?

Reading multiple files
Hi,
I have 35 data files for reading. I would like get a program for
performing reading of 35 files at once.
All are of the type: Dados1.raw, Dados2.raw and so on.
If the files have the same number of columns, I can read with the
following commands:
rm(list=ls())
filenames = list.files(path="~/Silvano/Arq", pattern="Dados+.*raw")

Extracting columns
Hi,
I have 22 files (A1, A2, ..., A22) with different number of columns,
totaling 10,000 columns: c1, c2, c3, ..., c10000
I have another file with a list of 100 columns that I need to extract.
These 100 columns are distributed in 22 files.
How to extract the 100 columns of the 22 files?
I have done it "manually" with the following commands, for example:

Hi,
How do I build a table from a regression model adjusted
using xtable?
Commands are:
modelo1 = lm(Y~X1 + X2)
influencia = influence.measures(modelo1)
require(xtable)
xtable(influencia)
but it isn't work.
Thanks,

regression analysis
Hi,
I have to do 10,000 linear regression analysis, and the response variable
(RESP) is the same for all independent variables (10,000).
y ~ x[i]
i = 1, ..., 10000
For each analysis must extract the p-value and put them in an orderly
increasing.
I thought an analysis of the type:
ana = numeric(10000)
for(i in 1:10000){
mod = lm(RESP~x[i]
p-value[i] = summary(mod)$coe[2,4]
}

Hi,
I'm fitting a model with 3 variables: A, B and SNP.
The response variable is Y.
I would like fit the following model, in this order:
Y ~ A + B + A*B + SNP
In general, the R sets of the form:
Y ~ A + B + SNP + A*B

Tukey's table
Hi,
I'm building Tukey's table using qtukey function.
It happens that I can't get the values of Tukey's one degree

The program is:

gl <- c(1:30, 40, 60, 120) # degree freedom

Split Plot and Tukey

I did the analysis of variance of a split-plot and the
effect of treatment was significant.
I would like compare treatment means using Tukey.

help w/ nonlinear regression

Estimated B and T (the model's coeff, herein B=-8,50 and T=5,46) seem appropriate (at least visually) but are quite diff from those obtained w/ SPSS (Levenberg-Marquardt): B=-19,56 and T=2,37.

Warning en modelo ZINB
Muchas gracias por la respuesta. He mirado y los coeficientes no son altos
pero sí tengo una gran cantidad de ceros en la variable dependiente (más
del 90%). Sin embargo, al incluir otro tipo de variables independientes no
me da ese aviso, dejando la misma variable dependiente.
¿Cómo podría utilizar stan/rstan de forma sencilla para diagnosticar el
modelo?

Codigo
Carlos, capaz no me explique bien, va de nuevo...
Tengo un dataFrame con varias variables que describen Lotes (127), he
creado un código que calcula nuevas variables, re codifica otras y ordenas
otras tantas. Es muy laborioso correr ese código 127 veces por lo cual
quería hacer un sentencia (del tipo if() o repeat()), para obtener al final
todos los lotes procesados.
