Read MAgPIE-object from file

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

Usage

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.

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