运行下列代码，基于stringr:: colors() 生成了字符串color_string ```{r} set.seed(123) color_string <- colors() %>% sample(., size = 500) ``` - 筛选出color_string 中所有不包含数字且不以字母 "s"开头的颜色，保存为新的color_string。

好的，根据您的要求，以下是解决方案：

library(stringr)

# 设置随机数种子
set.seed(123)

# 生成颜色字符串
color_string <- colors() %>% 
  sample(., size = 500)

# 筛选出不包含数字且不以字母 "s"开头的颜色
color_string_new <- color_string[!str_detect(color_string, "^s|[0-9]")]

# 查看新的color_string
color_string_new

输出结果如下：
