It depends the complexity of your expression. If you are sure you don’t have nested brackets, and pairs of brackets always match, this will take everything outside the brackets: str <- "A1{0}~B0{1} CO{a2}NN{12}” gsub("\\{[^}]*\\}", " ", str) Philippe Grosjean > On 11 Dec 2015, at 14:50,

The gsub function is your friend. s <- "A1{0}~B0{1} CO{a2}NN{12}" gsub( "([^{}]*)\\{([^{}]*)\\}", "\\1 ", s ) gsub( "([^{}]*)\\{([^{}]*)\\}", "\\2 ", s ) but keep in mind that there are many resources on the Internet for learning about regular expressions... they are hardly R-specific. --

The goal of the comparison operators is to obtain a logical value. Why compare logical values... you clearly already have that? stopifnot( logicalvariable ) and stopifnot( !logicalvariable ) are sensible, but not stopifnot( logicalvariable == TRUE ) or stopifnot( logicalvariable == FALSE )
