I have created various "im" objects, but can't seem to save and load them. I
can save them, but as small files of less than 1Kb. Therefore, when they are
re-loaded, they cannot be plotted as images.
Any ideas please.
Thankyou.

Hi everyone,
I have a question about functions. I have two functions:
Sampling=function(fname,Total,nSample,nPatient){..return(list(Gmean,Gsd))}
Power=function(alfa,m1,m2,s1,s2,n1,n2){return(powe)}
I want to use "Gmean" and "Gsd" which are the returned values from
"Sampling" function,
Your example uses ordinal probit model. I am actually looking for ordinal logit
model.

Hi all,
My data has some positive and negative values, and I want to plot a
barchart. The problem is that the y-axis zero is somewhere in the
middle of the plot, and the graph starts with a negative value. How
can I make the negative values appear as bars that are going below the
y-axis zero?
So t

I am confused. What's missing in the output of MCMCpack?

Is anyone aware of an R package that implements Pedroni's FMOLS (Fully
Modified Ordinary Least Squares) package, for panel data with
non-stationary and co-integration?

Hi,
I'm trying to perform a Principal Component Analysis on meteorological
data with 10 predictors.
I use the library pcaMethods to obtain a lot of information (loadings,
scores, mean, standard deviation, etc).
How can I obtain the scores (new PC variables) for new values of weather
predictors
Sorry, just correcting the script!!!
Hi everybody,
I'm trying, without success, to avoid some variables labels to overlap on a
capscale (vegan package) object graph.
I was able to move the labels with the coding below, but it moves the entire
vector...
CAPobj<-CAPpotiFT
for(i in c(2:8))CAPobj$
