Remove backticks from a string — text_remove

This function removes backticks from a string.

Usage

text_remove_backticks(x, ...)

# S3 method for class 'data.frame'
text_remove_backticks(x, column = "Parameter", verbose = FALSE, ...)

Arguments

x: A character vector, a data frame or a matrix. If a matrix, backticks are removed from the column and row names, not from values of a character vector.
...: Currently not used.
column: If x is a data frame, specify the column of character vectors, where backticks should be removed. If NULL, all character vectors are processed.
verbose: Toggle warnings.

Value

x, where all backticks are removed.

Note

If x is a character vector or data frame, backticks are removed from the elements of that character vector (or character vectors from the data frame.) If x is a matrix, the behaviour slightly differs: in this case, backticks are removed from the column and row names. The reason for this behaviour is that this function mainly serves formatting coefficient names. For vcov() (a matrix), row and column names equal the coefficient names and therefore are manipulated then.

Examples

# example model
data(iris)
iris$`a m` <- iris$Species
iris$`Sepal Width` <- iris$Sepal.Width
model <- lm(`Sepal Width` ~ Petal.Length + `a m`, data = iris)

# remove backticks from string
names(coef(model))
#> [1] "(Intercept)"     "Petal.Length"    "`a m`versicolor" "`a m`virginica" 
text_remove_backticks(names(coef(model)))
#> [1] "(Intercept)"   "Petal.Length"  "a mversicolor" "a mvirginica" 

# remove backticks from character variable in a data frame
# column defaults to "Parameter".
d <- data.frame(
  Parameter = names(coef(model)),
  Estimate = unname(coef(model))
)
d

#> 2    Petal.Length  0.298311

#> 4  `a m`virginica -1.674092
