  type = c("ex", "si", "ve", "ty", "-", "ml", "ro", "qr", "vr"),
  hedgeParams = defaultHedgeParams
)

Value

Arguments

type

The type of the required linguistic hedge

Details

hedge() returns a function that realizes the selected linguistic hedge on its parameter:

• ex: extremely,

• si: significantly,

• ve: very,

• ty: typically,

• -: empty hedge (no hedging),

• ml: more or less,

• ro: roughly,

• qr: quite roughly,

• vr: very roughly.

This function is quite low-level. Perhaps a more convenient way to create linguistic expressions is to use the lingexpr() function.

Examples

    a <- horizon(ctx3(), 'sm')
    plot(a)
    h <- hedge('ve')
    plot(h)
    verySmall <- function(x) h(a(x))
    plot(verySmall)

    # the last plot should be equal to:
    plot(lingexpr(ctx3(), atomic='sm', hedge='ve'))
