resizableLabel {oce}

Variable Names in Adjustable Sizes

Description

Provide axis names in adjustable sizes, e.g. using T instead of Temperature, and including units as appropriate. Used by e.g. plot,ctd-method().

Usage

resizableLabel(
  item,
  axis = "x",
  sep,
  unit = NULL,
  debug = getOption("oceDebug")
)

Arguments

item

code for the label. The following common values are recognized: "absolute salinity", "along-spine distance km", "along-track distance km", "C", "conductivity mS/cm", "conductivity S/m", "conservative temperature", "CT", "depth", "direction", "distance", "distance km", "eastward", "elevation", "fluorescence", "frequency cph", "heading", "latitude", "longitude", "N2", "nitrate", "nitrite", "northward", "oxygen", "oxygen mL/L", "oxygen saturation", "oxygen umol/kg", "oxygen umol/L", "p", "phosphate", "pitch", "roll", "S", "SA", "sigma0", "sigma1", "sigma2", "sigma3", "sigma4", "sigmaTheta", "silicate", "sound speed", "spectral density m2/cph", "speed", "spice", "T", "theta", "tritium", "u", "v", "w", or "z". Other values may also be recognized, and if an unrecognized item is given, then it is returned, unaltered.

axis

a string indicating which axis to use; must be x or y.

sep

optional character string inserted between the unit and the parentheses or brackets that enclose it. If not provided, then getOption("oceUnitSep") is checked. If that exists, then it is used as the separator; if not, no separator is used.

unit

optional unit to use, if the default is not satisfactory. This might be the case if for example temperature was not measured in Celcius.

debug

optional debugging flag. Setting to 0 turns off debugging, while setting to 1 causes some debugging information to be printed.

Value

A character string or expression, in either a long or a shorter format, for use in the indicated axis at the present plot size. Whether the unit is enclosed in parentheses or square brackets is determined by the value of getOption("oceUnitBracket"), which may be "[" or "(". Whether spaces are used between the unit and these deliminators is set by psep or getOption("oceUnitSep").
