This function is a ‘sub-engine’ between the main summary statistics engine, ‘gx.stats’, and the gx.summary.* display functions, it does not generate any output to the current device. Its ‘sub-engine’ function is to select the required results from the gx.stats computations, and additionally compute 95% confidence bounds on means.
gx.summary(xx, log = log, iftell = iftell)name of the variable to be processed.
set log = TRUE if it is required to compute statistics following a log10 transformation of the data.
passes the value of iftell for controlling the display of the NA count to function remove.na from the calling function.
a 15-element vector containing summary statistics, see below:
the sample size, N.
the number of NAs removed from the data passed for processing.
the minimum value, Q1, Median, Q3 and maximum value.
the Median Absolute Deviation (MAD).
the Inter-Quartile Standard Deviation (IQSD).
the data (sample) Mean.
the data (sample) Standard Deviation (SD).
the Coefficient of Variation as a percentage (CV%).
the Standard Error (S.E.) of the Mean.
the Lower 95% Confidence Limit on the Mean.
the Upper 95% Confidence Limit on the Mean.
The returned table is rounded to 4 significant figures.
