Bracket helpers

If you have table values that take the form point estimate (uncertainty estimate), you can use these functions to access specific parts of the table value.

bracket_drop(x, bracket_left = "(", bracket_right = ")")

bracket_extract(
  x,
  bracket_left = "(",
  bracket_right = ")",
  drop_bracket = FALSE
)

bracket_insert_left(x, string, bracket_left = "(", bracket_right = ")")

bracket_insert_right(x, string, bracket_left = "(", bracket_right = ")")

bracket_point_estimate(x, bracket_left = "(", bracket_right = ")")

bracket_lower_bound(
  x,
  bracket_left = "(",
  separator = ",",
  bracket_right = ")"
)

bracket_upper_bound(
  x,
  bracket_left = "(",
  separator = ",",
  bracket_right = ")"
)

Arguments

x

a character vector where each value contains a point estimate and confidence limits.

bracket_left

a character value specifying what symbol is used to bracket the left hand side of the confidence interval

bracket_right

a character value specifying what symbol is used to bracket the right hand side of the confidence interval

drop_bracket

a logical value (TRUE or FALSE). If TRUE, then the symbols on the left and right hand side of the interval will not be included in the returned value. If FALSE, these symbols will be included.

string

a character value of a string that will be inserted into the left or right side of the bracket.

separator

a character value specifying what symbol is used to separate the lower and upper bounds of the interval.

Value

a character value with length equal to the length of x.

Examples

tbl_value <- "12.1 (95% CI: 9.1, 15.1)"
bracket_drop(tbl_value)
#> [1] "12.1"
bracket_point_estimate(tbl_value)
#> [1] "12.1"
bracket_extract(tbl_value, drop_bracket = TRUE)
#> [1] "95% CI: 9.1, 15.1"
bracket_lower_bound(tbl_value)
#> [1] "9.1"
bracket_upper_bound(tbl_value)
#> [1] "15.1"
