Descriptive statistics
Description
This function is useful to see the basic statistical information of a variable.
Usage
destatWH(x, dec = NULL, op = FALSE)
Arguments
x |
Numeric. A vector containing the data set. |
dec |
Numeric. A value defined to set the number of decimals in the returns. |
op |
Logical. If TRUE, returns plot, histogram, boxplot and qqnorm of the data set. |
Details
This function shows statistical values including several visual tools.
Value
If op=FALSE (defined by default), the function returns a matrix (1 row, 9 columns) with values of the mean, the standart deviadtion, the minumun, the median, the maximum, the variance, the variation coefficient, the first quartil value and the third quartil value of the data set. Whereas if op=TRUE , the function returns four graphics: 1) A plot with X axis the number of samples and Y axis the amount of values included in the data set, 2) The density histogram of data set with a red line representing the distribution shape of the data, 3) A classical boxplot of the data, and 4) the qqnorm plot including the qqline used to check the normal disribution in a data set through visual inspection.
Examples
#Example 1
data=rnorm(1000,30,10)
destatWH( x=data ,dec=2 )
#Example 2
destatWH( x=data , op=TRUE )
