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().

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

## Arguments

item code for the label. This must be an element from the following list, or an abbreviation that uniquely identifies an element through its first letters: "S", "C", "conductivity mS/cm", "conductivity S/m", "T", "theta", "sigmaTheta", "conservative temperature", "absolute salinity", "nitrate", "nitrite", "oxygen", "oxygen saturation", "oxygen mL/L", "oxygen umol/L", "oxygen umol/kg", "phosphate", "silicate", "tritium", "spice", "fluorescence", "p", "z", "distance", "distance km", "along-track distance km", "heading", "pitch", "roll", "u", "v", "w", "speed", "direction", "eastward", "northward", "depth", "elevation", "latitude", "longitude", "frequency cph", "sound speed", or "spectral density m2/cph". a string indicating which axis to use; must be x or y. 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. optional unit to use, if the default is not satisfactory. This might be the case if for example temperature was not measured in Celcius. 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").
