has.Chg: Check for Bid, Ask, Mid, and/or Trade columns in data
In qmao: Quantmod Add-on

Description Usage Arguments Details Value Author(s)

A set of functions to check for appropriate BAM and BATM column names within a data object, as well as the availability and positions of those columns.

  has.Chg(x, which = FALSE)

  has.AskSize(x, which = FALSE)

  has.BidSize(x, which = FALSE)

  is.BAM(x)

  has.BAM(x, which = FALSE)

  has.BATM(x, which = FALSE)

  is.BATM(x)

`x`	data object
`which`	display position of match

is.BAM (and is.BATM, similarly) will only return TRUE if there are columns for Bid, Ask, Mid (and Trade for is.BATM). Additional columns will not affect the value.

A logical value indicating success or failure by default.

If which=TRUE, a numeric value representing the column position will be returned.

is.BAM and is.BATM return a single value of TRUE or FALSE.
