Error: '~/AppData/Local/Temp/RtmpWgW3LK/names.csv' does not exist.

Great job on making an R package for fuzzy mining! I am currently trying to use it on my own data and have a question. When creating the metrics with mine_fuzzy_model() R gives the following error:

Error: '~/AppData/Local/Temp/RtmpWgW3LK/names.csv' does not exist.

Which is true, but I don't know how to solve this error. Is there an easy fix or am I doing something completely wrong? I would appreciate your help!

Thanks for reporting this. We have seen this issue in different situations on and off, but it is a bug that is hard to reproduce.

Can you try removing special chars from the names of the events and give it a try?

[stijndelaat]

Thank you for the quick response. Unfortunately this did not solve the problem. There were special characters in the names, but I have removed them:

log2 <- df3 %>%
  create_eventlog(
    case_id = "case",
    activity_id = "RegPhase",
    timestamp = "Time",
    resource_id = "Subject"
  )

Can you tell me what OS you are using and more details about the OS like version, etc?

Also, can I know your R version that comes out when you use the "version" command in the R console?

Thanks!

So I looked through this file https://github.com/nirmalpatel/fuzzymineR/blob/master/R/mine_fuzzy_model.R trying to figure out what might be going wrong...

I'm trying to figure out whether this is a Windows-specific issue or not... You can see that all of the file paths are constructed using file.path() so that looks fine. Do you have Java installed? We invoke a JAR file on line 155...

One of the things you can check is, you can source the function in your own file after loading the package (override it essentially) and then try and see till what line it runs fine. You can just use the browser() function at the start of the function and you'll know where it is throwing an error...

[stijndelaat]

I have Java installed (V8. update 271).

Guess this is the point where my knowledge in R stops :). I have no idea what a JAR file is or how to properly source a function from a package and how to use the browser function the way you mean.

I have tried the following: test<-fuzzymineR:::mine_fuzzy_model Then opened "test" via the global environment and ran the code line by line. It threw an error when I hit line 28: cli_template <- read_lines(cli_template_fpath) Error in read_lines(cli_template_fpath) : could not find function "read_lines"

Am I right in thinking that this is not the big error we were looking for, but it is due to the way I tried to look for the error?
