Read a file in Bremen format.

read.bremen(file, encoding = "latin1")



a connection or a character string giving the name of the file to load.


a character value that indicates the encoding to be used for this data file, if it is textual. The default value for most functions is "latin1", which seems to be suitable for files containing text written in English and French.


A bremen object.


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


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.
