I'm running R version 3.3.2 (64-bit), python version 2.7.12 (32-bit) on Windows 8.1 (64-bit). I have installed fuzzywuzzyR as well as corresponding python packages: fuzzywuzzy, Levenshtein

I tried the following:

s1 = ' It was a dark and stormy night. I was all alone sitting on a red chair.'
s2 = ' It was a murky and stormy night. I was all alone sitting on a crimson chair.'
init <- FuzzMatcher$new()
init$Partial_ratio(string1 = s1, string2 = s2)

I received the following error message upon running the last statement:
"Error in init$Ratio(string1 = s1, string2 = s2) :
attempt to apply non-function"

I also observed the following:

check_availability()
[1] FALSE

Is there a fix for this problem? All the online articles showed positive result while testing the functions of FuzzMatcher class.

R Studio crashes when trying to use dplyr and fuzzywuzzyR at the same time.
Simple example:
library(fuzzywuzzyR)
library(dplyr)
--> R Session Aborted.
--> R encountered a fatal error.
--> The session was terminated.

library(fuzzywuzzyR)
word = "安广"
choices = c("安徽","安广")
init_proc = FuzzUtils$new()      # initialization of FuzzUtils class to choose a processor
PROC = init_proc$Full_process    # processor-method
init_scor = FuzzMatcher$new()    # initialization of the scorer class
SCOR = init_scor$WRATIO          # choosen scorer function
init <- FuzzExtract$new()        # Initialization of the FuzzExtract class
init$Extract(string = word, sequence_strings = choices, scorer = SCOR)

When I use the above code, I find that the result are all 0. Is that means that this package cannot work properly when dealing with Chinese characters?

The package used to work well (just 3 months ago in fact), but recently, when I use parts of it, I'm getting this error:

Error in DIFFLIB$get_close_matches(string, sequence_strings, n, cutoff) :
attempt to apply non-function

I do have python installed, as well as all the other dependencies, and it worked 3 months ago (I had no issues then).

Here's my output for reticulate::py_discover_config(required_module = 'fuzzywuzzy') in case that helps:

What might be happening? Thanks!

Dear Developer,

I'm trying to develop an app where it computes inti$WRATIO(string1, string2). If I execute the same code in "global.R" it generates the output & also If I deploy it locally.

However, If I deploy the same app on Shinyappsio, deployment is successful with an error message on the web-page as "An error has occurred. Check your logs or contact the app author for clarification.". When I check the logs,

Also please find the screenshot of the app after successful deployment,

When I execute locally output is fine as below screenshot,

Kind help is greatly appreciated!!!

Hi,

if I try to run your example, the code is below, I get the following error:
"Error in init$Extract(string = word, sequence_strings = choices, processor = PROC, :
attempt to apply non-function"

I tried with both package versions, the one in Cran and in Github.

This is the code which generates that error:

library(fuzzywuzzyR)
word = "new york jets"

choices = c("Atlanta Falcons", "New York Jets", "New York Giants", "Dallas Cowboys")

processor :

init_proc = FuzzUtils$new() # initialization of FuzzUtils class to choose a processor

PROC = init_proc$Full_process # processor-method

PROC1 = tolower # base R function ( as an example for a processor )

scorer :

init_scor = FuzzMatcher$new() # initialization of the scorer class

SCOR = init_scor$WRATIO # choosen scorer function

init <- FuzzExtract$new()

Initialization of the FuzzExtract class

init$Extract(string = word, sequence_strings = choices, processor = PROC, scorer = SCOR)
