将IMDb数据读入R

Question

我需要读取IMDb通过FTP公开可用的数据here。问题是数据并不总是一致的格式。我在下面附加了一小段数据（前几行）。

我试过使用read.table()与sep = '\t'，但它不会以100％的精度分割线条。

Here你可以找到样本数据。

如何将此表读入R？

Answer 1

使用普通readLines然后strsplit每行\\t+。

file <- readLines("PATHTO/actorstest.txt", encoding = 'Latin-1') 

# delete empty rows 
file <- subset(file, !grepl('^\\s*$', file)) 

# split in two columns by one or more tabs 
file <- strsplit(x = file, split = '\\t+') 

# row bind all itms and create df 
df <- data.frame(do.call(rbind, lapply(file, unlist))) 
df
