PCA with tow response variables
...and I don't have a clue how to do... and I've only used the simplest PCAs before, like this:
pcaObj=prcomp(t(df[idx, c(40:47)]))
biplot(pcaObj)
Anyone who knows how to do?
Best rageds,
Joel

Exchange NAs for mean
...{
if(is.na(X[j,i])) # Search for missing value in the given position
{
X[j,i]=mean(X[1:p, i]) # Change missing value to the mean of the column
}
}
}
All the best,
Joel

Exclude rows in xyplot
...above. I've found that limits can be used in a similar manner as with xlim and ylim, but though I've read about them I don't understand how to solve it... Anyone who can help me?
All the best,
Joel

Plot overview xy plots from data frame?
...cause they are not grouped and there are 20 additional non-numerical columns in the data frame.
By the way, can the iterations be made using R, or do you have to combine with for instance Perl?
All the best,
Joel

PCA analysis
Hi,
I have a problem with making PCA plots that are readable.
I would like to set different sympols instead of the numbers of my samples or their names, that I get plotted (xlabs).
How is this possible? With points, i don´t seem to get the right data plotted onto the PCA plot, as I do not quite understand from where it is taken. I dont know how to
plot the correct columns of the prcomp
