The encodeString() function in R is used to encode character strings in various ways, particularly for ensuring correct alignment and handling of special characters.
Syntax
encodeString(x, width = 0, quote = "", na.encode = TRUE,
justify = c("left", "right", "centre", "none"))
Parameters
- x: It is a character vector or an object coerced to one by as.character.
- width: It is an integer: the minimum field width. If NULL or NA, this is the largest field width needed for any element of x.
- quote: It is a character: quoting character, if any.
- na.encode: It is a logical argument: should NA strings be encoded?
- justify: It is a character: partial matches are allowed. If padding to the minimum field width is needed, how should spaces be inserted? justify == “none” is equivalent to width = 0, for consistency with format.default.
Return Value
It returns a character vector of the same length as x, with the same attributes but no class set.
Common uses
- It can be used when formatting text for output, such as in plot labels or printed tables.
- It can also manage special characters, like quotes or escape sequences, in strings.
- Create neatly formatted tables for console output.
Example 1: Basic usage
x <- "ps5\nnvidia\nrestock"
print(x)
cat("interprets escapes", "\n")
cat(x, "\n")
cat("After using encodeString", "\n")
cat(encodeString(x), "\n", sep = "_")
Output
[1] "ps5\nnvidia\nrestock"
interprets escapes
ps5
nvidia
restock
After using encodeString
ps5\nnvidia\nrestock_
Example 2: Using with Vector
rv <- c("outriders", "returnal", "rangnarok")
encodeString(rv)
encodeString(rv, 2)
encodeString(rv, width = NA)
encodeString(rv, width = NA, justify = "c")
encodeString(rv, width = NA, justify = "r")
encodeString(rv, width = NA, quote = "'", justify = "r")
Output
[1] "outriders" "returnal" "rangnarok"
[1] "outriders" "returnal" "rangnarok"
[1] "outriders" "returnal " "rangnarok"
[1] "outriders" "returnal " "rangnarok"
[1] "outriders" " returnal" "rangnarok"
[1] "'outriders'" " 'returnal'" "'rangnarok'"
