Read MAgPIE-object from file

Reads a MAgPIE-file and converts it to a 3D array of the structure (cells,years,datacolumn)

read.magpie(
  file_name,
  file_folder = "",
  file_type = NULL,
  as.array = FALSE,
  comment.char = "*",
  check.names = FALSE,
  ...
)

`file_name`	file name including file ending (wildcards are supported). Optionally also the full path can be specified here (instead of splitting it to file_name and file_folder)
`file_folder`	folder the file is located in (alternatively you can also specify the full path in file_name - wildcards are supported)
`file_type`	format the data is stored in. If file_type=NULL the file ending of the file_name is used as format. If format is different to the formats mentioned standard MAgPIE format is assumed. See `write.magpie` for a list of supported file formats.
`as.array`	Should the input be transformed to an array? This can be useful for regional or global inputs, but all advantages of the magpie-class are lost.
`comment.char`	character: a character vector of length one containing a single character or an empty string. Use "" to turn off the interpretation of comments altogether. If a comment is found it will be stored in attr(,"comment"). In text files the comment has to be at the beginning of the file in order to be recognized by read.magpie.
`check.names`	logical. If TRUE then the names of the variables in the data frame are checked to ensure that they are syntactically valid variable names. Same functionality as in read.table.
`...`	additional arguments passed to specific read functions (e.g. `varname` for specifying the variable to be read in from a multi-variable NCDF file.)

See write.magpie for a list of supported file formats.

`x`	MAgPIE-object

See write.magpie for the detailed structure of binary MAgPIE formats .m and .mz.
