这是我的数据集的一个列变量的一些示例值，我想以下列方式拆分列：
> top[1:5,6]
[1] Scroll, mounted and framed, ink and colour on paper \n 34 x 95 cm. (13 3/8 x 37 3/8 in.)
[2] Scroll, mounted and framed, ink and colour on paper \n 34.3 x 68.3 cm. (13 1/2 x 26 7/8 in.)
[3] Scroll, mounted and framed, ink and colour on paper \n 67 x 34 cm. (26 3/8 x 13 3/8 in.)
[4] Scroll, mounted and framed, ink on paper \n 135 x 68 cm. (53 1/8 x 26 3/4 in.)
[5] Hanging scroll, ink and colour on paper \n 80 x 28 cm. (31 1/2 x 11 in.)
并删除括号中的内容。
我怎样才能实现这一点，因为这是\ n而逗号是分隔符？至少，我想要分开媒体和大小。
R的新手，非常感谢任何帮助

我得到了这个结果。
x <- "Scroll, mounted and framed, ink and colour on paper \n 34 x 95 cm. (13 3/8 x 37 3/8 in.)"
strsplit(x, ", | \n | \\(.+")
#[[1]]
#[1] "Scroll" "mounted and framed"
#[3] "ink and colour on paper" "34 x 95 cm."

<form action='scratch_clean' method='get'>
<input id='return' />
<input id="no_return" />
<input type='submit' />
</form>
<div id='result'></div>
<script type="text/javascript">
$(document).ready(function() {
$('#no_return').on('keyup', function(e) {
e.preventDefault();
var code = e.which;
if(code==13)
{
$('#result').append('keyup<br>');
return false;
}
//return false; // not needed
});
$('form').on('submit', function(e) {
e.preventDefault();
$('#result').append('submit<br>');
// EDIT: Other processing happens here
return false;
});
});

如果您想要数据框结果
data <- c("Scroll, mounted and framed, ink and colour on paper \n 34 x 95 cm. (13 3/8 x 37 3/8 in.)" ,

"Scroll, mounted and framed, ink and colour on paper \n 67 x 34 cm. (26 3/8 x 13 3/8 in.)" ,
"Scroll, mounted and framed, ink on paper \n 135 x 68 cm. (53 1/8 x 26 3/4 in.)" ,
"Hanging scroll, ink and colour on paper \n 80 x 28 cm. (31 1/2 x 11 in.)")
res <- strsplit(gsub("\\. *\\([^)]+\\)" , "" , data ) , ",|\n")
# [[1]]

根据显示的示例，我们可以移除\n以及(之后带有gsub的字符。根据使用外观显示的文字插入,，并使用vector
read.table/read.csv（'top1'）
top1 <- gsub('\\s*\\(.*$|[\n]', '', top)
read.table(text=gsub('(?<=(?i)scroll,)\\s+(?=ink)|(?<= on paper)\\s+',
',', top1, perl=TRUE), sep=',', header=FALSE, stringsAsFactors=FALSE)
# V1 V2 V3 V4
#1 Scroll mounted and framed ink and colour on paper 34 x 95 cm.
#2 Scroll mounted and framed ink and colour on paper 34.3 x 68.3 cm.
#3 Scroll mounted and framed ink and colour on paper 67 x 34 cm.
#4 Scroll mounted and framed ink on paper 135 x 68 cm.
#5 Hanging scroll ink and colour on paper 80 x 28 cm.
top <- c('Scroll, mounted and framed, ink and colour on paper \n 34 x 95 cm. (13 3/8 x 37 3/8 in.)',
