Setting up infile for R CMD BATCH
Suppose I create an R program called myTest.R with only one line like
the following:
type <- as.integer(readline("input type (1: type1; 2: type2)? "))
Then I'd like to run myTest.R in batch mode by constructing an input
file called answers.R with the following:
source("myTest.R")

Data.frames can not hold objects...What can be done in the following scenario?
R-Help community,
I understand that data.frames can hold elements of type double, string
etc but NOT objects (such as a matrix etc). This is not convenient for
me in the following situation. I have a function that takes 2 inputs
and returns a vector:
testfun <- function (x,y) seq(x,y,1)
I have a data.frame defined as follows:
testframe<-data.frame(xvalues=c(2,3),yvalues=c(4,5))
I would

xyplot and abline
Dear All,
I wonderif there is a simple way to draw a regression line in the xyplot:
more specifically, let:
age <- c(20:30, 31:40 )
age.cut <- cut(age, breaks = 2 )
y<- rnorm(20)
x <- rnorm(20,4,1)
xyplot(y ~ x| age.cut, xlab="x", ylab="y")
How to draw (in the plot given by xyplot) the two regression lines (y ~ x) corresponding to the two category

Package "demography" - calculating percentiles of survival probabilities distribution
Hi,
I am using the package "demography" from Rob Hyndman for the
Lee-Carter-Model. It is an amazing powerful tool but I am struggling with
one issue:
I want to compute different percentiles of the survival probability
distribution derived from the Lee-Carter-Forecast (e.g. the 50%tile,
60%tile, 75%tile and 99%tile) for each of the next 10 years. Is there any
possibility to retrieve

Is there an lm() equivalent of panel.lmline()?
panel.lmline returns intercept and slope of y ~ x subsetted to the
combination of conditioning factors given to xyplot in lattice.
for instance:
xyplot(Xvalues ~ log(Qvalues)|Tfac, data = df7, panel = panel.lmline)
I am looking to find the equivalent formulation for lm() proper. If I do
this:
lmcal <- lm(Xvalues ~ log(Qvalues):Tfac, data = df7)
Only one value of the intercept is returned.

Prettier axis labels when using log scales in Lattice
Hello,
I am trying to alter the way in which lattice functions (specifically xyplot) print the axis labels when one uses the 'scales' parameter.
I can obtain the effect I want by using
scales=list(y=list(log=10, labels=expression(yvalues)))
where yvalues are the values that would have been printed as the y-axis labels if the "labels" argument had not been present. To help

purrr::pmap does not work
Hi All,
I try to do a scatterplot for a bunch of variables. I plot a dependent

keep adding elements to the matrix
Hello everyone,
I would like to create a "dynamic" array to keep storing number in it
for (i in c(2:length(final))){
myarray <-final[i]-final[i-1]
myarray2<-2*final[i]
}
At the end I would like to use myarray as the x values of an array
and the myarray2 as the yvalues of the same array.
I tried cbind but it didnot work.
Could you please help me with that?

abline(v= x) in plot with time formated xaxis not working
Hi,
I try to create a vertical line in my plot, which has a xaxis comprising
time formated data.
This is what I tried:
----------------
y<-152833
x<-strptime(y, format="%H%M%S")
abline(v=x, col="red")
----------------
for some reason, it doesn't work and no error msg is displayed...
I hope someone can tell me what I do wrong, or maybe an alternative.
Thanks

Constructing bar charts with standard error bars
I am new to R.
I want to graph group data using a "Traditional Bar Chart with Standard
Error Bar", like the kind shown here:
http://samiam.colorado.edu/~mcclella/ftep/twoGroups/twoGroupGraphs.html
Is there a simple way to do this?
So far, I have only figured out how to plot the bars using barplot.

error bar position setting
Hi,
I am using R on Windows XP.
I am using 'arrows' funtion to plot the variance as error bar, BUT error
bar goes only one side of the data point, I need to plot the error bar on
both side of the data point (plot is attached), I am using following
commands to plot,

I have succeeded in fitting a GAMLSS.dist model to growth data I am working
with it.
My aim is to create a matrix of predicted percentiles and the corresponding

Hola,
Esta es una forma de hacerlo...
Mira que lo primero que he modificado es el fichero "x.csv" para sustituir
los espacios en los nombres por "_". Y también he quitado los acentos y las
eñes...
He utilizado el paquete RNNS y la función "mlp()" para ajustar la red.
