R: Limit the magnitude of elements of a vector

limit {elliptic}

R Documentation

Limit the magnitude of elements of a vector

Deals appropriately with objects with a few very large elements

limit(x, upper=quantile(Re(x),0.99,na.rm=TRUE),
         lower=quantile(Re(x),0.01,na.rm=TRUE),
         na = FALSE)

`x`	Vector of real or complex values
`upper`	Upper limit
`lower`	Lower limit
`na`	Boolean, with default `FALSE` meaning to “clip” `x` (if real) by setting elements of `x` with `x>high` to `high`; if `TRUE`, set such elements to `NA`. If `x` is complex, this argument is ignored

If x is complex, low is ignored and the function returns x, after executing x[abs(x)>high] <- NA.

x <- c(rep(1,5),300, -200)
limit(x,100)
limit(x,upper=200,lower= -400)
limit(x,upper=200,lower= -400,na=TRUE)
