Couldn't see a solution online but I thought this might be quite common.
无法在线查看解决方案，但我认为这可能很常见。
- with
write.csvI basically always have the argumentrow.nameset to F. Is it possible to run a line once and update the default value of the argument for the rest of the session? - 使用write.csv我基本上总是将参数row.name设置为F.是否可以运行一次行并更新会话其余部分的参数的默认值？
- I tried
paste <- paste(sep="")which ran and returned no error but seemed to do nothing (and didn't destroy thepastefunction). This is another one, I always setsep=""withpaste... - 我尝试粘贴< - paste（sep =“”）运行并返回没有错误，但似乎什么都不做（并没有破坏粘贴功能）。这是另一个，我总是用贴纸设置sep =“”...
- like I always have
exclude=NULLwhen I am usingtableso I can see the N/A values. - 就像我在使用表时总是有exclude = NULL所以我可以看到N / A值。
EDIT: So, I'm looking for a solution that will work for multiple functions if possible: paste, write.csv, table and other functions like these.
编辑：所以，我正在寻找一种解决方案，如果可能的话，它将适用于多种功能：paste，write.csv，table和其他类似的功能。

Try this:
尝试这个：
paste <- paste
formals(paste)$sep <- ""
This creates a new copy of paste in your workspace, and then modifies its default value for sep to "". Subsequent calls to paste will then use the modified copy, as it sits in front of the base environment in your search path.
这会在工作区中创建一个新的粘贴副本，然后将sep的默认值修改为“”。随后对粘贴的调用将使用修改后的副本，因为它位于搜索路径中的基础环境之前。

paste <- paste(sep="") puts the output of paste() into an object named "paste". You would need to do something like this instead.
paste < - paste（sep =“”）将paste（）的输出放入名为“paste”的对象中。你需要做这样的事情。
paste <- function (..., sep = "", collapse = NULL) {
base::paste(..., sep=sep, collapse=collapse)
}
You can also look at the Defaults package for this sort of thing, but it doesn't currently work for two of your examples.
您还可以查看Defaults包中的这类内容，但它目前不适用于您的两个示例。
