There was an error rendering this rich post.

I love the functionality of dynamic unpivot for transforming my data vertically, I would love to see a similar functionality for adding columns

I think I got this to work using the R scripts. I did it in 2 steps, because I am not that savvy in R.

!!!— here is the first Rscript tile, the purpose of this is to make all the names of my new columns in a format R can use, the column that houses my names is called PARTNO —-!!!

Import the domomagic library into the script.

library('domomagic')
library('janitor')
library('tidyverse')

read data from inputs into a data frame

input1 <- read.dataframe('Filter Rows')

write your script here

input1 <- input1 |>
mutate(
PARTNO = tolower(PARTNO),
PARTNO = trimws(PARTNO),
PARTNO = gsub("[^[:alnum:]]", "", PARTNO),
PARTNO = gsub("+", "_", PARTNO)
)

write a data frame so it's available to the next action

write.dataframe(input1)

!!!—- this is the second tile, I am making columns with the name in PARTNO, and the vlues from DATA1—-!!!

Import the domomagic library into the script.

library('domomagic')
library('tidyverse')
library('janitor')

read data from inputs into a data frame

input1 <- read.dataframe('Select Columns')

write your script here

input2 <- pivot_wider(
input1,
names_from = PARTNO,
values_from = DATA1,
values_fill = 0
)

write a data frame so it's available to the next action

write.dataframe(input2)
