我正在通过public class User {
private String fullName;
private String emailAddress;
private String currentAddress;
private String phoneNumber;
public class User {
private String fullName;
private String emailAddress;
private String currentAddress;
private String phoneNumber;
public User(String fullName, String emailAddress, String currentAddress, String phoneNumber) {
this.fullName = fullName;
this.emailAddress = emailAddress;
this.currentAddress = currentAddress;
this.phoneNumber = phoneNumber;
}
public String getFullName() {
return fullName;
}
public String getFullName() {
return fullName;
}
public String getFullName() {
return fullName;
}
public String getFullName() {
return fullName;
}
}
和H2O使用R,但是H2O崩溃了。我想查看日志,但是包含R临时目录的R临时目录似乎在R会话结束时(即Rscript完成时)被删除了。
是否可以告诉R / Rscript不要删除它使用的tmp文件夹?
答案 0 :(得分:1)
为此,一种解决方法是使用on.exit
获取临时文件并将其保存在其他目录中。一个示例函数如下所示:
ranfunction <- function(){
#Get list of files in tempdir
on.exit(templist <- list.files(tempdir(), full.names = T,pattern = "^file") )
#create a new directory for files to go on exit
#use add = T to add to the on.exit call
on.exit(dir.create(dir1 <- file.path("G:","testdir")),add = T )
#for each file in templist assign it to the new directory
on.exit(
lapply(templist,function(x){
file.create(assign(x, tempfile(tmpdir = dir1) ))})
,add=T)
}
ranfunction()
此功能未考虑的一件事是,如果重新运行它-因为新目录dir1
已存在,将引发错误。重新运行脚本之前,您必须删除dir1
。
