Read a file in Bremen format, producing an object inheriting from
bremen-class.
read.bremen(file)a connection or a character string giving the name of the file to load.
An object of bremen-class.
This function may be renamed (or removed) without notice. It was created to read some data being used in a particular research project, and will be rendered useless if Bremen changes this data format.
Velocities are assumed to be in
cm/s, and are converted to m/s to follow the oce convention. Shears
(which is what the variables named uz and vz are assumed
to represent) are assumed to be in (cm/s)/m, although they could be in 1/s
or something else; the lack of documentation is a problem here. Also,
note that the assumed shears are not just first-difference estimates
of velocity, given the results of a sample dataset:
> head(data.frame(b[["data"]])) pressure u v uz vz 1 0 0.092 -0.191 0.00000 0.00000 2 10 0.092 -0.191 0.02183 -0.35412 3 20 0.092 -0.191 0.03046 -0.09458 4 30 0.026 -0.246 -0.03948 0.02169 5 40 -0.003 -0.212 -0.02614 0.03111 6 50 -0.023 -0.169 -0.03791 0.01706
