comparison_replace: Replacing Values by Comparison

In inops: Infix Operators for Detection, Subsetting and Replacement

Description

Operators for replacing values using the standard comparison operators.

Usage

x >= y <- value

x > y <- value

x <= y <- value

x < y <- value

x == y <- value

x != y <- value

Arguments

x	first element of the operation.
y	second element of the operation.
value	replacement value.

Details

Thanks to these operators :

• x == y <- value is equivalent to x[x == y] <- value

• x != y <- value is equivalent to x[x != y] <- value

• x <= y <- value is equivalent to x[x <= y] <- value

• x >= y <- value is equivalent to x[x >= y] <- value

• x < y <- value is equivalent to x[x < y] <- value

• x > y <- value is equivalent to x[x > y] <- value

Value

x with values for which the comparisons evaluate to TRUE replaced with value.

Examples

ages <- c(130, 10, 1996, 21, 39, 74, -2, 0)

ages == 1996 <- as.numeric(format(Sys.Date(), "%Y")) - 1986
ages

ages > 100 <- NA
ages

ages <= 0 <- NA
ages
