Print character strings without quotes.

Keywords
methods, utilities, print
Usage
noquote(obj, right = FALSE)

# S3 method for noquote print(x, quote = FALSE, right = FALSE, …)

# S3 method for noquote c(…, recursive = FALSE)

Arguments
obj

any R object, typically a vector of character strings.

right

optional logical eventually to be passed to print(), used by print.default(), indicating whether or not strings should be right aligned.

x

an object of class "noquote".

quote, …

further options passed to next methods, such as print.

recursive

for compatibility with the generic c function.

Details

noquote returns its argument as an object of class "noquote". There is a method for c() and subscript method ("[.noquote") which ensures that the class is not lost by subsetting. The print method (print.noquote) prints character strings without quotes ("\dots").

If right is specified in a call print(x, right=*), it takes precedence over a possible right setting of x, e.g., created by x <- noquote(*, right=TRUE).

These functions exist both as utilities and as an example of using (S3) class and object orientation.

Examples
library(base) # NOT RUN { letters nql <- noquote(letters) nql nql[1:4] <- "oh" nql[1:12] cmp.logical <- function(log.v) { ## Purpose: compact printing of logicals log.v <- as.logical(log.v) noquote(if(length(log.v) == 0)"()" else c(".","|")[1 + log.v]) } cmp.logical(stats::runif(20) > 0.8) chmat <- as.matrix(format(stackloss)) # a "typical" character matrix ## noquote(*, right=TRUE) so it prints exactly like a data frame chmat <- noquote(chmat, right = TRUE) chmat # } # NOT RUN { <!-- %dont --> # }
