grep在R中没有正确搜索 [英] grepl not searching correctly in R

问题描述

我想在向量中搜索.com，但grepl不适合我。有人知道为什么我正在做以下工作：

I want to search ".com" in a vector, but grepl isn't working out for me. Anyone know why? I am doing the following

vector <- c("fdsfds.com","fdsfcom")
grepl(".com",vector)

返回

This returns

[1] TRUE TRUE

我想要它请严格引用fdsfds.com。

I want it to strictly refer to "fdsfds.com"
