R语言read.table读取tsv文件

a <- read.table("filename",header = F,sep = "\t",fill = F)

第一次尝试代码

read.table("downloads/homologene/btd/orthologs_search_106586_5-15-2022.tsv",header = F,sep = "\t",quote = "\"'",fill = F,dec = ".")

出现如下报错

Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec, : line 67 did not have 11 elements

添加了fill = T后

read.table("downloads/homologene/btd/orthologs_search_106586_5-15-2022.tsv",header = F,sep = "\t",fill = T)

成功导入

原因：原文件中有缺失值导致报错，可以使用fill=TRUE对缺失值进行填充，
