当我在R中传递给定的下面的参数时
wordcloud(words[1:200], frequency[1:200], min.freq = 70)
wordcloud(words[1:200], frequency[1:200], max.words = 19)
It is showing this error: 它显示此错误：
Error in if (min.freq > max(freq)) min.freq <- 0 : missing value where TRUE/FALSE needed

It's likely that frequency contains NA values; frequency可能包含NA值; remove them: 删除它们：
wordcloud(words[!is.na(frequency)], freqs[!is.na(frequency)])

It is because you probably have a NA in your frequency vector. 这是因为你的frequency向量中可能有一个NA 。 I could replicate your problem with this: 我可以用这个复制你的问题：
wordcloud(c("test","test2","test20","test200","test2000"),freq=c(75,40,NA,100,10),min.freq=10) wordcloud（C（ “测试”， “TEST2”， “test20”， “test200”， “test2000下”），FREQ = C（75,40，NA，100,10），min.freq = 10）
