使用vcf2geno代码时R会话中止

试图让这段代码再次运行，我已不再感到沮丧。这段代码以前工作过，我提交了完整的作业，但我试图将其用于我的项目，现在运行这段代码会导致R中止会话

代码如下：

library(LEA)
setwd("/Users/Changirwa/Desktop/COURSES/BIOL 468")

vcf2geno(input.file = "data/pika_subset.vcf", output.file = "data/pika_subset.geno")

geno2lfmm(input.file = "data/pika_subset.geno", output.file = "data/pika_subset.lfmm")

我试图编织文件，看看它会说什么，它是这样说的：

*已捕获故障*

地址0x0，导致“内存未映射”

Traceback:
