我正在使用Jamovi处理Excel文件中数据集的一些变量。

jmv::descriptives(
  formula = country ~ `voted`,
  data = bd,
  bar = TRUE,
  missing = FALSE,
  mean = FALSE,
  median = FALSE,
  sd = FALSE,
  min = FALSE,
  max = FALSE)

当我导入代码并尝试执行代码以获取图形时，出现以下错误：

Warning messages:
1: In FUN(X[[i]], ...) : no non-missing arguments to max; returning -Inf
2: In mean.default(x, na.rm = TRUE) :
  argument is not numeric or logical: returning NA
3: In mean.default(x, na.rm = TRUE) :
  argument is not numeric or logical: returning NA
4: In mean.default(x, na.rm = TRUE) :
  argument is not numeric or logical: returning NA
5: In var(if (is.vector(x) || is.factor(x)) x else as.double(x), na.rm = na.rm) :
  NAs introduced by coercion
6: In var(if (is.vector(x) || is.factor(x)) x else as.double(x), na.rm = na.rm) :
  NAs introduced by coercion
7: In var(if (is.vector(x) || is.factor(x)) x else as.double(x), na.rm = na.rm) :
  NAs introduced by coercion

我错过了什么？
