R doesn't know whether the missing (NA) value is 6 or not, so by
default it returns it so the user can make up her own mind.
If you're using square brackets for subsetting, you need to explicitly

them.

Hi,
thank you for taking the time and reading my question. My question is
twofold:
1. I have several matrices with variables and one matrix with water levels.
I want to predict the water level with the data in the other matrices.
A few general comments about stepwiseAIC and a suggestion of how to select
models
a) Apart form the problem, that stepwise selection is not a garanty to get the
best model, you need to have a lot of data to avoid overfitting if your model
includes 7 parameter plus interactions ( 10
Both solutions work great. Thank you for your help.

I am writing to ask your opinion on how to interpret this case. I have two

So you think a t-test is more adequate to use in this case ?

Hi R User,
I calculated a correlation matrix and I was trying to give a same name for rows
and columns (heading) in the correlation matrix. But, I was not able to do so.
Would you mind let me know how I can assign the same name for the heading of
row and columns in the matrix?
I appreciate

It does that automatically. Just assign the names you want to the data.frame
before you compute the correlation matrix:
x - data.frame(matrix(rnorm(100), ncol=5))
colnames(x) - c(A, B, C, D, E)
y - cor(x)
y
A B C D E
A 1.
Hi All,
I have used windows R.
We can also write like this:
A - read.csv(C:/Users/Anthi/Desktop/R/A.csv,header=TRUE)
