R hist（）错误消息：无效的休息数

Question

我一直试图查看我的数据分布以查看它是否正常并使用r中的hist（）函数。它最初工作，我看到数据非常左倾，所以我尝试记录转换它，我收到错误消息＆＃34;无效的休息次数＆＃34;。我在Mac上使用r studio Version 1.0.136，这是我在Microsoft Excel中作为csv文件的数据集示例：

我的代码：

#Import my dataset
library(readr)
LeafWaterPotentials <- read_csv("~/Desktop/LeafWaterPotentials.csv", col_types = cols(Block = col_factor(levels = c("1", "2", "3")), Solute.Potential = col_number(), Treatment = col_factor(levels = c("nID", "ID", "nInD", "InD")), Vapro.Reading = col_number(), WP = col_number(), leaf.turgor.potential = col_number(), water.potential.Mpa = col_number()))

#check whether the data has normal distribution
hist(LeafWaterPotentials$Solute.Potential) #distribution is skewed

#try log-transforming data (also tried sqrt and get same error)
hist(log(LeafWaterPotentials$Solute.Potential))

输出：

  

hist.default中的错误（日志（LeafWaterPotentials $ Solute.Potential））：
    无效的休息次数＆＃39;

#Check summary of dataset
summary(LeafWaterPotentials)

输出：

summary(LeafWaterPotentials)

这是截图，因为编码输出看起来有点混乱：

我对r比较新，但我想知道这个错误是否与NA值有关，但之前我已经用NA创建了对数转换数据的直方图，并且没有问题。
