Analysis on R

Hi there,
I began using R last week and... It drives me crazy!
However, I'm using the package "AnalyzefMRI" and that's right, but I have some problems related to atomic vector.
Here's my code:

>library(AnalyzeFMRI)

Error in hdr$dim :$ operator is invalid for atomic vectors

It's ok, until the last command.
Any help? What's the problem on the header file?
I understood the story about atomic, recursive, matrix and vectors, but I can't see how it's linked to my case... Thanks!:wave:

Hi,

Did you find a solution? I'm having the same problem and receiving the same error message. I too have read the story about atomic, recursive, matrix, and vectors and cannot see how it relates to the problem. Thanks!

Hi!

Just to let you know, my problem was in the earlier code.

for (t in 1: length(files)) {file = files[t]; img = f.read.analyze.volume(file)[, , slice, 1]; data[, , t] <- img}

My variable slice was out of bounds and for some reason this gave me the error:
Error in hdr$dim :$ operator is invalid for atomic vectors

When I reduced the value of slice, the commands ran smoothly.

Hi everybody!
Yes, I solved the problem. In my case it was a problem of format: my images were DICOM, but f.read.analyze.volume can read only Analyze format :yup:
