Summary

Extended summary function for numeric objects, with 13 summary statistics.

Usage

smry(x, ...)

# S3 method for default
smry(x, na.rm=TRUE, digits = max(3, getOption("digits")-3), ...)

# S3 method for zoo
smry(x, na.rm=TRUE, digits = max(3, getOption("digits")-3), ...)

# S3 method for Date
smry(x, na.rm=TRUE, digits = max(3, getOption("digits")-3), ...)

# S3 method for matrix
smry(x, na.rm=TRUE, digits = max(3, getOption("digits")-3), ...)

# S3 method for data.frame
smry(x, na.rm=TRUE, digits = max(3, getOption("digits")-3), ...)

Arguments

x: a numeric object, vector, matrix or data.frame, for which a summary is desired.
na.rm: a logical value indicating whether 'NA' values should be stripped before the computation proceeds.
digits: numeric, with the amount of decimal places to be included in the result
...: further arguments passed to or from other methods.

Value

Computed summary statistics are:

Min: Minimum
1stQ: First quartile (lower-hinge)
Mean: Mean value
Median: Median
3rdQ: Third quartile ( upper-hinge
Max: Maximum of the input values.
IQR: Interquartile Range. IQR(x) = quantile(x,3/4) - quantile(x,1/4)
sd: Standard deviation. It uses 'n-1' as denominator.
cv: Coefficient of variation ( cv= sd / |mean| )
skewness: Skewness (using e1071 package)
kurtosis: Kurtosis (using e1071 package)
n: Total number of elements
NA's: Amount of missing values

Note

Skewness and Kurtosis are computed with the e1071 package
