我想在R中创建一个带有长字符串列表的向量，但由于某种原因，代码运行时不会产生错误或生成向量。据我所知，代码中没有语法错误。
myvars <- c("sale_year", "sale_mnth", "end_duration_mean", "ln_end_duration_mean", "one_by_end_duration_mean", "end_duration_class_2_dummy_mean", "end_duration_class_3_dummy_mean",

如果列表中的某个字符串出现问题，我已尝试缩小范围，但是将列表拆分为较短的列表，我可以在某些时候将所有字符串包括在内。
由于过去我能够创建更长的向量（就变量数量而言），我对于出了什么问题感到茫然。 提前致谢
答案 0 :(得分：1)
R读取的行的宽度有限，将命令拆分为多行可以解决问题。我不确定我们是否可以更改设置以增加R读取的行的长度。以下命令有效：
