strsplit()是一个字符串切割的函数。在R语言中,使用strsplit()函数可以将一个字符串按照指定的分隔符进行切割。该函数的语法为strsplit(x, split, fixed = FALSE, perl = FALSE, useBytes = FALSE)。其中,x是待切割的字符串,split是分割符。函数返回一个列表类型的结果,每个元素都是切割后的子字符串。在stringr包中也有一个与之类似的函数str_split(),其语法为str_split(string, pattern, n = Inf, simplify = FALSE)。该函数与strsplit()的参数simplify设置为TRUE时的效果一致。此外,还有一个C语言中的函数strsplit(),其函数原型为uint8_t **strsplit(uint8_t *str,uint8_t *Separator),用于将一个字符串str按照特定的分隔符Separator进行切割,返回分割后的子字符串列表指针。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
