Removes measure of centrality from the series

Removes the mean, the median or the mode from the series.

demean(x, na.rm = getOption("transx.na.rm"))

demedian(x, na.rm = getOption("transx.na.rm"))

demode(x, na.rm = getOption("transx.na.rm"))

Arguments

x	[univariate vector] Univariate vector, numeric or ts object with only one dimension.
na.rm	[logical(1): getOption("transx.na.rm")] A value indicating whether NA values should be stripped before the computation proceeds.

Value

Returns a vector with the same class and attributes as the input vector.

Examples

x <- c(2,5,10,20,30)
summary(x)
#>    Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
#>     2.0     5.0    10.0    13.4    20.0    30.0 

demean(x)

demedian(x)
#> [1] -8 -5  0 10 20
demode(x)
