<p>Prezados,<br>
<br>
A algum tempo, questionei na lista sobre a existência de uma função <br>
para quebra de linha<br>
automática para títulos de gráficos.<br>
<br>
Após a sugestão do Benilton (função gsub), segue abaixo o código... <br>
caso necessitem.<br>
<br>
## Pre-Processa titulos<br>
<br>
pretitulo <- function(orig, cut=55) {<br>
nparts = ceiling(nchar( orig) / cut)<br>
cuts = c(1,1:nparts * cut)<br>
spt = strsplit(orig, "\\s")[[1] ]<br>
cs = cumsum(nchar( spt))<br>
<br>
ids <- matrix(FALSE, nparts,length( nchar(spt) ))<br>
for(i in 2:length(cuts) ) {<br>
ids[i-1,] <- (cs >= cuts[i-1] & cs < cuts[i])<br>
}<br>
<br>
ch <- vector("character" , nparts)<br>
for(i in 1:nparts) {<br>
ch[[i]] <- paste(spt[ids[ i,]],collapse = " ")<br>
}<br>
pretitulo <- paste(ch,collapse= "\n")<br>
}<br>
<br>
Não é o melhor, computacionalmente falando, mas funciona :)<br>
<br>
Abraços<br>
