R中Sys.getenv('SLURM_ARRAY_TASK_ID')返回NA的报错问题咨询

运行的R代码 #

cur_dir<-"C:/Users/child/Dropbox/Proteogenomics_analysis/Proteome and Phosphoproteome Data     Normalization/Experiment_data_20230222_Metabric_multistate_analysis"
setwd(cur_dir)
library(mstate)
library(brcarepred)

id <- as.numeric(Sys.getenv("SLURM_ARRAY_TASK_ID"))
print(id)
load("./Models/FourGroupsM.RData")
timepoints <- seq(from=0, to=20, by=0.25)
pt <- list()
newdata.DR <- newdata
newdata.DR$AGE.DR[which(newdata.DR$strata %in% seq(from=9,by=9, length=4))] <- newdata.DR$AGE.DR[which(newdata.DR$strata %in% seq(from=9,by=9, length=4))] + newdata.DR$TLastSurgery[which(newdata.DR$strata %in% seq(from=8, by=9, length=4))]
pt[['DR']] <- getProbsDR(m, group=id, newdata.DR, timepoints=timepoints)

报错信息 #

pt[['DR']] <- getProbsDR(m, group=id, newdata.DR, timepoints=timepoints)
Error in group:(group + 8) : NA/NaN argument

排查结果 #

执行id <- as.numeric(Sys.getenv("SLURM_ARRAY_TASK_ID"))后，输出结果为NA：

id <- as.numeric(Sys.getenv("SLURM_ARRAY_TASK_ID"))
print(id)
[1] NA

疑问 #

• 不理解Sys.getenv("SLURM_ARRAY_TASK_ID")语句的作用是什么？
• 运行该脚本前需要创建什么文件？请提供示例说明。
