Convert an R object into a YAML string

Convert an R object into a YAML string

as.yaml(x, line.sep = c("", "", ""), indent = 2, omap = FALSE, column.major = TRUE)
x{ the object to be converted }
  line.sep{ the line separator character(s) to use }
  indent{ the number of spaces to use for indenting }
  omap{ determines whether or not to convert a list to a YAML omap; see Details }
  column.major{ determines how to convert a data.frame; see 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

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