Convert an R object into a YAML string

Description

Convert an R object into a YAML string

Usage

  as.yaml(x, line.sep = c("\n", "
\n", "
"), indent = 2, omap = FALSE,
          column.major = TRUE, unicode = TRUE, precision = getOption('digits'))

Arguments

Details

If you set the omap option to TRUE, as.yaml will create ordered maps (or omaps) instead of normal maps.

The column.major option determines how a data frame is converted. If TRUE, the data frame is converted into a map of sequences where the name of each column is a key. If FALSE, the data frame is converted into a sequence of maps, where each element in the sequence is a row. You'll probably almost always want to leave this as TRUE (which is the default), because using yaml.load on the resulting string returns an object which is much more easily converted into a data frame via as.data.frame.

Value

Returns a YAML string which can be loaded using yaml.load or copied into a file for external use.
