qcc con par
Hola colegas, por favor si me indican que estoy haciendo mal.
Estoy tratando de usar el paquete QCC y colocar mas de gráfico de control
en una sola ventana usando función "par" con "qcc" para presentar varios
gráficos en la misma ventana.
He probado pero no funciona, solo muestra un gráfico miren el código
# set unequal sample sizes
n <- c(rep(50,5), rep(100,5), rep(25, 5))

Tracing gradient during optimization
...to see more output of the optimization procedure, in particular
the numerical gradient of the parameter vector during each iteration.
The documentation of optim() describes that the trace parameter should allow
one to trace the progress of the optimization.
I use the following command:
optim(par = vPar,
fn = calcLogLik,
method = "BFGS",
control = list(trace = TRUE, fnscale = -1, maxit = 2000));
which gives very little information:
initial value 3.056998
final value 2.978351
converged
Specifying trace >1, for instance trace = 20, does not result in more...

gplot problems with faceting
....Biofilm_C"
Then I try the following, but I get an error message :
> qp<- qplot(Par.Value, Var.Value, data = z[z$Var==v,], ylab=v, geom=c("point","smooth"), method="lm")
> qp<- qp + facet_wrap( facets= Par~ ., scales = "free_x", ncol=length(vPar))
> qp
Erreur dans `[.data.frame`(plot$data, , setdiff(cond, names(df)), drop = FALSE) :
colonnes non d?finies s?lectionn?es
I can have this working by modifying the facets arguments to "Par~Var", and it does what I want,
But it is not satisfying, and I am confused with this error...

Excel to R
Hello R-help
I am trying to copy and paste large column of data from windows Excel into R
base speed sheet using:
Data1<-edit(data.frame())
But I can only copy and paste one cell at a time which is time consuming.
Also how can assign each column to a variable.

Linear regression - several response variables vs few ind variables
Hi all,
I need to run several simple linear regressions at once, using the
following data. Response variables: Bird species (sp 1, sp2, sp3...spn).
Independent variable: Natprop - proportion of natural area. covarate:
Effort = hours). One single linear regression would be: lmSp1 <- lm(sp1~
natprop + effort). However, I need to run this linear regression for all
bird species that I have

If you're saying that the scp protocol is an unfixable mess then the
openssh team has been agreeing[0] with you for at least a decade and a
half. We fix what we can, but some

Linear multivariate regression with Robust error
Dear all,
i am doing linear regression with robust error to know the effect of
a (x) variable on (y)other if i execute the command i found positive
trend.
But if i check the effect of number of (x.x1,x2,x3)variables
on same (y)variable then the positive effect shwon by x variable turns
to negative. so plz help me in this situation.
