I am trying to create a new column ("pct_change") within an existing dataframe that was imported from SQLServer.
The following code worked in R Studio:
library(dplyr)
df1 <- df1 %>%
group_by(employeeid) %>%
arrange(fiscalyear, .by_group = TRUE) %>%
mutate(pct_change = ((Salary/lag(Salary) - 1) * 100))
I then modified the above code from "df1" to "dataset" but was unable to get it to work. Could someone please help me?
Solved! Go to Solution.
Hi @Anonymous ,
I use the code below and new column is created.
library(stats) library(base) library(dplyr) df1 <- dataset %>% group_by(employeeid) %>% arrange(fiscalyear, .by_group = TRUE) %>% mutate(pct_change = ((Salary/lag(Salary) - 1) * 100))

How and where did you save that code block within Power BI?
Thanks, Icey! I didn't realize you had to import R base and stats.
Hi @Anonymous ,
Can you give me your error information? So that I can help you better.
