我在阅读此标签分隔表GO_MF.txt到R
以下是我输入的部分内容：
YAL004W YAL004W Unknown
YAL005C SSA1 unfolded protein binding ATPase activity
YAL007C ERP2 molecular_function
YAL008W FUN14 molecular_function
YAL009W SPO7 phosphoprotein phosphatase activity
YAL012W CYS3 cystathionine gamma-lyase activity
YAL013W DEP1 molecular_function
YAL014C SYN8 SNAP receptor activity
YAL017W PSK1 protein serine/threonine kinase activity
当我在excel中打开它时完全没问题：3606行，最多11列。
但是，当我尝试使用以下命令将此表输入到R中时：
no_col <- max(count.fields("GO_MF.txt", sep = "\t"), na.rm=T)
pop <- read.table("GO_MF.txt", sep = "\t",fill = TRUE, as.is=T, col.names=1:no_col)
我发现只有2284个障碍物。 11个变量。当我在Rstudio中View(pop)时，我发现有一个单元格似乎无法识别\ t和\ n（见下文）：
