One fairly easy option is to just center and scale each of the x-variables,
then fit your model on the transformed variables. This works best if your
x-variables are roughly symmetric mound shaped and could be meaningless if
any of the x-variables is highly skewed or has outliers.

Hello,
I have estimated the coefficients for my model using the 'pggls' function
from the 'plm' package. Now I want to see the relative influence of those
X's. How can some please tell me how to standardize those my results in R?
Thank you!

Dear all,
I have a dataframe:
df-dataframe(a=c(1,2,3),b=c(4,5,6),c=c(7,8,9),d=c(10,11,12))
I want to obtain a new dataframe with columns a and b being standardized
((x-mean(x))/sd(x)); the other two columns (c,d) I want to leave
unchanged. What is the best way to achieve this? I have been

If you want to scale within columns, you could try
cbind( scale(df[,1:2]), df[ ,-c(1:2)] )
a b c d
1 -1 -1 7 10
2 0 0 8 11
3 1 1 9 12
and it is data.frame() btw.

I suspect you might have tried (df-mean(df))/sd(x) and gotten

yes, indeed! a few times, but why is that?

Very quick newbie question sorry;
How do I standardize a list of data please (other than do the calculation of
course). Is there a quick way please ?

Hi,
Maybe you are looking for

Dear list,
I'm writing a long document (thesis) and as much as I would like to
use only ggplot2 for the graphics, some features are still a bit
undocumented so I often end up choosing either ggplot2, lattice, or
base plots (which i know better) depending on the particular graph to
11 matches
