r - R 包中的变量标签 Haven with SPSS

Question

我正在尝试从带有haven 包的SPSS por 文件访问变量标签(这是变量的描述)。我可以用外国包做得很好，但我想使用haven。有什么建议？

# Using foreign I can get the variable labels
with_foreign <- foreign::read.spss(mydata.por)
attr(with_foreign, "variable.labels")

# With haven I get null
with_haven <- haven::read_spss(mydata.por)
attr(with_haven, "variable.labels")

# Some things I've experimented with
labelled::var_label(with_haven) # NULL
attributes(with_haven) # Not useful
as_factor(with_haven$var1) # Gives me definitions for factor levels (not what I need)

Answer 1

如 read_spss 中所述标签存储为每列的属性，而不是 data.frame 的属性。 .尝试

lapply(with_haven, function(x) attributes(x)$label)
