我的問題是我有一個包含 200 多個變數的資料集，有些是數字的，有些是分類的（編碼為 0 或 1）。我的目標是使用ggplot2條形圖來顯示分類資料與數值資料的兩個條形。
我面臨的另一個問題是我也不知道如何識別哪些列是連續的，哪些是分類的，因為使用 str只給我第一個 ~90 列的細分，而不是其余的。對不起，如果這是一個非常初學者的問題，但我正在嘗試建立我的 R 技能，這個問題讓我難住了。
我腦子里的計劃是以某種方式制作 2 列（可能使用summarise），一列是分類資料，另一列是數字，然后使用geom_col用來制作圖表，但它沒有按照我的計劃進行。
我已經放置了資料的 dput，這僅包括資料的前 6 行（其中有一百萬行）。
編輯：我只記得這summary是一個函式，我可以用它來獲取所有列的摘要。所以這是識別哪些列是數字/分類列的一種方法。

所有列都是數字
df1[, which(sapply(.SD, is.numeric))]
如果我們正在尋找特定的值，即 0 和 1
binary <- df1[, which(sapply(.SD, function(x) all(c(0, 1) %in% x)))]
conti <- setdiff(seq_along(df1), binary)
它可以用
>df1[, sum(sapply(.SD, is.numeric))]
[1] 287
> ncol(df1)
[1] 287
uj5u.com熱心網友回復：
您可以將該class函式與 a 一起使用sapply來獲取所有列型別。
這里我做了一個小例子：
df = data.frame(matrix(as.numeric(runif(10*10)),ncol = 10),
matrix(sample(c(0L, 1L), size = 100, replace = TRUE), ncol = 10))
sapply(df, class)
您的二進制列將顯示為“整數”。
