parallel.melt: Melt multiple sets of columns in parallel

In mudata: Interchange Tools for Multi-Parameter Spatiotemporal Data

Description

Essentially this is a wrapper around reshape2::melt.data.frame that is able to cbind several melt operations. This is useful when a wide data frame contains uncertainty or flag information in paired columns.

Usage

parallel.melt(x, id.vars, ..., variable.name = "param",
  factorsAsStrings = TRUE)

Arguments

x	A data.frame
id.vars	vector of ID variable names
...	Named arguments specifying the measure.vars to be stored to the column name specified.
variable.name	Column name to use to store variables
factorsAsStrings	Control whether factors are converted to character when melted as measure variables.

Value

A qtag.long object

Examples

data(pocmajsum)
parallel.melt(pocmajsum,
              id.vars=c("core", "depth"),
              values=c("Ca", "Ti", "V"),
              err=c("Ca_sd", "Ti_sd", "V_sd"))
