Convert R script to powerbi function

[sontt]

Hi there

I try convert my string to sha256 with r-script function:

library(digest)
apikey <- "hello"
apimessage <-"world"
hash <- digest::hmac(apikey,apimessage, algo="sha256", serialize=F)

I found  similar thread here : https://community.powerbi.com/t5/Desktop/Invoke-Function-writtein-in-R/td-p/87438 

but i still cant convert to powerbi function.

This is my file: https://drive.google.com/open?id=1wrZQgzeW8uvy7cNRWKPuiqICYhPfp6wc

Please help me convert it.

Thank you so much

Hi sontt,

To achieve your requirement, please refer to R Script:

# 'dataset' holds the input data for this script

library(digest)

len <- length(dataset[[1]])

hash <- c()

for (i in 1:len) {

    hash <- append(hash, digest::hmac(dataset[i, 1],dataset[i, 2], algo="sha256", serialize=F))

}

dataset$hash <- hash

result <- dataset

 

The result is like below and you can refer to PBIX file here:
