我正在尝试运行VariableSelection功能MaxentVariableSelection但遇到错误说

read.table 中的错误(file = file,header = header,sep = sep,quote = quote,:输入中没有可用的行

这是我正在使用的代码,

MaxentVariableSelection::VariableSelection(maxent="c:/Users/Piyali/Downloads/Software/maxent/maxent.jar", 
              outdir="/Users/Piyali/Desktop/msc_paper/R_SDM/outputtest", 
              gridfolder="/Users/Piyali/Desktop/msc_paper/R_SDM/30sclippedascii",
              occurrencelocations="/Users/Piyali/Desktop/msc_paper/R_SDM/occ_full.csv",
              backgroundlocations="/Users/Piyali/Desktop/msc_paper/R_SDM/bg_full.csv",
              additionalargs="additionalargs",
              contributionthreshold=5, 
              correlationthreshold=0.9,
              betamultiplier=seq(2,6,0.5))

请问有什么办法解决这个问题吗?
