我正在尝试从CCES中提取元数据。
当我下载R（.Rdata）的文件，然后加载它（<Style TargetType="ListBoxItem" x:Key="ListViewStyle">

）时，它会一直说load("/Users/DanielEGreen/Downloads/CCES12_Common_VV.RData")。
我已将其移至各种文件夹（例如/ Users / DanielEGreen / School /等等），但似乎没有任何让步。
在我的g.environment中，有114,155个障碍物的数据，但显示的是1个变量，即RDX2。
我是R和元数据收集的半新手;我之前已经提取过GSS信息，但那是因为您可以下载.csv文件，我知道如何将其直接附加到R。
答案 0 :(得分：0)
使用以下方式加载数据对我来说很好：
df <- load("CCES12_Common_VV.RData")
您的RData可能位于错误的目录中。如果不使用完整路径，则文件必须位于工作目录中。您可以使用getwd()检查您的工作目录。然后，您需要将工作目录设置为RData文件所在的文件夹setwd()。
或者，您可以在加载RData文件时指定完整路径。
