So I have a character vector with currency values that contain both dollar signs and commas. However, I want to try and remove both the commas and dollar signs in the same step.
所以我有一个货币值包含美元符号和逗号的字符向量。但是，我想尝试在同一步骤中删除逗号和美元符号。
This removes dollar signs =
这会删除美元符号=
d = c("$0.00", "$10,598.90", "$13,082.47")
gsub('\\$', '', d)
This removes commas =
这会删除逗号=
library(stringr)
str_replace_all(c("10,0","tat,y"), fixed(c(","), "")
I'm wondering if I could remove both characters in one step.
我想知道我是否可以一步删除这两个字符。
I realize that I could just save the gsub results into a new variable, and then reapply that (or another function) on that variable. But I guess I'm wondering about a single step to do both.
我意识到我可以将gsub结果保存到一个新变量中，然后在该变量上重新应用该（或另一个函数）。但我想我想知道一步到位。

Since answering in the comments is bad:
由于评论中的回答很糟糕：
gsub('\\$|,', '', d)
replaces either $ or (|) , with an empty string.
用空字符串替换$或（|）。

take a look at ?regexp for additional special regex notation:
看一下？regexp以获得额外的特殊正则表达式：
> gsub('[[:punct:]]', '', d)
[1] "000" "1059890" "1308247"
