Params with vector

Publishing Your Results
1

Hi,
i would like to create a script in R with params, can I create a params as vector?
For example:
I have this command: mutate(cluster=case_when((offert=="xxx" & prod %in% c("a","b") & year==params$year1 & month %in% c(2,3,4,5) ) ~"Cluster1")
I would like to replace c(2,3,4,5) with params$months , but if i set params with months: c(2,3,4,5) it doesn't work, cluster is NA.
How can i solve this?

Hello.
Thanks for providing code , but you could take further steps to make it more convenient for other forum users to help you.

Share some representative data that will enable your code to run and show the problematic behaviour.

You might use tools such as the library datapasta, or the base function dput() to share a portion of data in code form, i.e. that can be copied from forum and pasted to R session.

This is an example:

Sample:

|ID|prodotto_cod|year|month|
|1|SGSTD|2022|3|
|2|SGP|2021|11|
|3|SGP|2022|2|
|4|SGE|2022|5|
|5|SGSTD|2022|5|
|6|SGE|2022|5|
|7|SGBAS|2022|3|
|8|SGPRE|2022|4|
|9|SGP|2022|3|
|10|SGBAS|2021|3|

title: "Example"
author: ""
date: "22/09/2022"
params:
year0: 2021
year1: 2022
months: c(2,3,4,5)
n_months: 4
output:
html_document: default
word_document: default


#example without params
example_without_params <- example %>% 
    mutate(cluster=case_when((prodotto_cod %in% c("SGSTD","SGBAS") & year==2022 & month %in% c(2,3,4,5)) ~"Cluster1",
                           (prodotto_cod %in% c("SGPRE") & year==2022 & month %in% c(2,3,4,5)) ~ "Cluster2"))

#what would i like do
example_with_params <- example %>% 
    mutate(cluster=case_when((prodotto_cod %in% c("SGSTD","SGBAS") & year==params$year1 & month %in% params$months) ~"Cluster1",
                           (prodotto_cod %in% c("SGPRE") & year==params$year1 & month %in% params$months) ~ "Cluster2"))
#in this case all cluster in NA, params$months doesn't work

Define the vector like this: !r c(2,3,4,5)

title: "Example"
author: ""
date: "22/09/2022"
params:
  year0: 2021
  year1: 2022
  months: !r c(2,3,4,5)
  n_months: 4
output:
  html_document: default
