I'm trying to write a single format file within the arules package, to load it in as a transaction afterwards for association rule mining. I can't use this function, since R keeps using the base::write function instead of the arules::write function.

arules::write(x = dfSingle,

              file = "dfSingleFile",

              format = "single",

              quote = TRUE,

              sep = ",")

Gives the following error message:

Error in base::write(x, file, ...) : 

unused arguments (format = "single", quote = TRUE)

When I loaded the arules package at the beginning of the session, it did say it masked the write function from base:

library(arules)

Loading required package: Matrix



Attaching package: ‘arules’

The following objects are masked from ‘package:base’: abbreviate, write

I've already tried installing the arules package again. I'm using R 3.5.1 within Rstudio Server (1.1.414).

Any help on this?

Check the class of dfSingle, if it is not "transactions" then it is passed to base::write, see example:

library(arules)

data(Epub)



class(Epub)

# [1] "transactions"

# attr(,"package")

# [1] "arules"

arules::write(x = head(Epub),

              file = "test",

              format = "single",

              quote = TRUE,

              sep = ",")

# no errors!



class(mtcars)

#[1] "data.frame"

arules::write(x = mtcars,

              file = "test",

              format = "single",

              quote = TRUE,

              sep = ",")

# Error in base::write(x, file, ...) : 

#   unused arguments (format = "single", quote = TRUE)
