Reads a file from the SwissMetNet of MeteoSwiss containing multiple Exports

Description

One peculiarity of MeteoSwiss is to provide multiple exports concatenated in one file, starting with a line containing a single space and seperated by two newlines. This function reads the whole file into the memory, splits the part and applies the read function to each part. Is the file too big for the available memory, the function split_smn() can split the file into multiple files each containing one part. On Linux the commandline tool csplit is another probably faster tool.

Usage

read_smn_multiple(fn, as_list = FALSE, encoding = "UTF-8", ...)

Arguments

fn	path to input file
as_list	return a list with each part as element rather than one concatenated tibble
encoding	encoding of the data file. Default = "UTF-8"
...	parameters passed to read_smn()

Value

tibble or list of tibbles in rOstluft long format structure
