logT

Log transformation of stratigraphic series.

Routines for astrochronologic testing, astronomical time scale construction, and time series analysis <doi:10.1016/j.earscirev.2018.11.015>. Also included are a range of statistical analysis and modeling routines that are relevant to time scale development and paleoclimate analysis.

logT function

<dl> <dt>dat</dt>
<dd>Stratigraphic series for log transformation. Input can have any number of columns desired. If two or more columns are input, the first column must be location (e.g., depth), while remaining columns are data values for transformation.</dd> <dt>c</dt>
<dd>Constant to add prior to log transformation. Default = 0.</dd> <dt>opt</dt>
<dd>(1) use natural logarithm, (2) use log10. Default = 1.</dd> <dt>genplot</dt>
<dd>Generate summary plots? (T or F). This is automatically deactivated if more than one variable is transformed.</dd> <dt>verbose</dt>
<dd>Verbose output? (T or F)</dd></dl>
