我只是试图用几组相同的数据重复我几个月前所做的事情。 Comparing two dataframe in r
这些是我的数据框：
df1
> 1 2 3
> 1 AT GC CC
> 2 AG GC CT
> 3 GG TT <NA>
df2
> 1 2 3
> 1 AT <NA> GG
> 2 AG GC CG
> 3 GG TT AA
results I want
> 1 2 3
> 1 TRUE <NA> FALSE
> 2 TRUE TRUE FALSE
> 3 TRUE TRUE <NA>
我的两个dfs (df1,df2)的级别不同，所以我需要将它们更改为字符。
A <- lapply(df1, as.character)
B <- lapply(df2, as.character)
所以我做比较：
A == B
但我得到一个错误：
Error in A == B :
comparison of these types is not implemented
