Test if a file is an SWC format neuron

is.swc(f, TrustSuffix = TRUE)

## Arguments

f Path to one or more files Whether to trust that a file ending in .nrrd or .nhdr is a NRRD

logical value

## Details

Note that this test is somewhat expensive compared with the other file tests since SWC files do not have a consistent magic value. It therefore often has to read and parse the first few lines of the file in order to determine whether they are consistent with the SWC format.
