Format a point estimate plus confidence interval as a single string

Format a point estimate plus confidence interval as a single string

Usage

format_interval(median, lower, upper, digits = 2)

Arguments

median, lower, upper

Numeric (scalar or vector). median is the central value (a point estimate or the median of bootstrap replicates), lower and upper the confidence-interval endpoints.

digits

Integer rounding precision.

Value

Character like "5.12 [4.87, 5.4]". A non-finite median yields NA_character_ (rather than "NA [...]"); a non-finite bound is shown as an en dash, so the strings stay table-ready.

Examples

format_interval(5.123, 4.872, 5.401)
#> [1] "5.12 [4.87, 5.4]"
format_interval(NA, 1, 2)   # -> NA
#> [1] NA
