变异结果统计与绘图时，最后一步出现Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec, : line 17 did not have 34 elements的问题，查看文件发现并没有缺失的部分，怎么解决

运行Rscript $scriptdir/var_density.R -i snp.unknown_multianno.vcf -b 1000000 -c "darkgreen,yellow,red" -t "SNP Density"这条代码后出现Error in scan(file = file, what = what, sep = sep, quote = quote, dec = dec, :

line 17 did not have 34 elements的问题，

查看了第17行，34个元素都在，并没有缺失
