我正在尝试使用read_fwf()从美国人口普查局读取固定宽度的文件到R中。我在列名列表的同一位置不断收到错误消息。我尝试过多次尝试更改该位置的特定列名称，R不断抛出错误。我将R重新启动到新的会话，并不断收到错误消息。在列名列表中，似乎是有问题的是第39个项目。在我包含在代码中的一种尝试中，我更改了第39个位置的名称，有时也更改了第38个位置的名称。代码块中的第一行代码具有原始列名值。在该行中，第39个名称是“ cbsac”，但错误将其打印为“ ...”。它与第38位的名称“ cbsa”非常接近，但是列表其他部分中的许多连续名称非常相似，并且不会引起错误。我不知道该说些什么。 “ cbsac”是否意味着R中我不知道的东西？

这可以解决您的问题吗？
baseName=mlp
name1_G=mlpname..1
print(name1_G) -- output: mlp1
name1_G=CreateNN()
print(mlp1) --output: nil
