为什么使用粘贴创建的文件名中有空格? [英] why there is a gap in the file name created using paste?

问题描述

我试图使用R编写文件，并且为了区分每个文件，我试图每次在函数中添加一个不同的后缀.

I was trying to write a file using R and in order to distinguish each file, i tried to add a different suffix each time in a function.

例如……

    counts <- function(counts_file)
    {
     ..............................
     ..............................
     name <- substr(counts_file,1,5)
     file <- paste(name,".cpm.csv")
     write.csv(countpermillion, file)
     }

但是当我运行功能counts("JKNC1.bam.tsv")时，创建的输出文件就是这样的
JKNE3 .cpm.csv，即JKNEE3 and .cpm.csv之间存在间隙.我在这里做错什么了?

But when i run the function counts("JKNC1.bam.tsv"), the output file created is like this
JKNE3 .cpm.csv i.e there is a gap between the JKNEE3 and .cpm.csv. What am i doing wrong here?

谢谢 Upendra

推荐答案

默认分隔符为空格. paste(name,".cpm.csv",sep="")应该在这里做您想要的.或者，您可以使用

The default separator is a space. paste(name,".cpm.csv",sep="") should do what you want here. Alternately, you could use

paste0(name,".cpm.csv")

有关此文档，可以在控制台上键入?paste来找到.

The documentation for this can be found by typing ?paste at the console.
