英文:
"Coercing argument of type 'character' to logical" warning message for !any function
问题
I run this code to see if in depth I have "0-5cm", it works but I also get a warning message that I don't understand, anyone know?
if (isTRUE(!any(depth) %in% "0-5cm")) {print("yes")} else {print("no")}
[1] "yes"
Warning message:
In any(depth) : coercing argument of type 'character' to logical
我运行这段代码来查看depth中是否有 "0-5cm", 它可以运行，但我也收到了一个我不理解的警告消息，有人知道吗？
if (isTRUE(!any(depth) %in% "0-5cm")) {print("yes")} else {print("no")}
[1] "yes"
Warning message:
In any(depth) : coercing argument of type 'character' to logical

请注意你的 any 后面的闭括号。由于 any 的输出已经是逻辑值，你不需要 isTRUE。我不确定你是否有意在 any 前面加了取反符号 (!)。
depth <- c(letters, "0-5cm")
[1] "a" "b" "c" "d" "e" "f" "g"
[8] "h" "i" "j" "k" "l" "m" "n"
[15] "o" "p" "q" "r" "s" "t" "u"
[22] "v" "w" "x" "y" "z" "0-5cm"
if ("0-5cm" %in% depth) {print("yes")} else {print("no")}
[1] "yes"
英文:
Note the closing bracket of your any. You don't need isTRUE since the output of any is already logical. Not sure if you're intensionally negating (!) any.
depth <- c(letters, "0-5cm")
[1] "a" "b" "c" "d" "e" "f" "g"
[8] "h" "i" "j" "k" "l" "m" "n"
[15] "o" "p" "q" "r" "s" "t" "u"
[22] "v" "w" "x" "y" "z" "0-5cm"
if (any("0-5cm" %in% depth)) {print("yes")} else {print("no")}
[1] "yes"

你的括号使用有些混淆。
如果你想评估你的 if 条件，你需要更像这样：
if (!any(depth %in% "0-5cm")) # 寻找特定的在其中在逻辑上有点不合理，即使它起作用
此外，不知道 depth 的结构是什么样的，我假设它是一个向量？
如果是这种情况，我建议将你的语句改为：
!any("0-5cm" %in% depth) # 寻找多个中的特定内容
英文:
You are mixing up your parenthesis.
If you want to asses your if condition you need something more like:
if(!any(depth %in% "0-5cm")) # looking for the many in the specific makes logically little sense, even if it works
Also not knowing how depth looks like, i assume it is a vector?
If this is the case I'd advise to turn your statement around to:
!any("0-5cm" %in% depth) # looking for the specific within the many
