I’m wondering how to replace all Inf and NaN elements in numeric columns in my OUTPUT with NA in a pipe chain?
I tried the following without success:
OUTPUT %>% replace(is.infinite(.)|!is.numeric(.), NA)
library(tidyverse)
DATA <- structure(list(InstID = c(2063L, 2063L, 2063L, 2063L, 2113L,
2113L, 2113L, 2113L, 2440L, 2441L, 2441L, 2441L),
InstNm = c("Adel SD 21", "Adel SD 21", "Adel SD 21", "Adel SD 21", "Adrian SD 61",
"Adrian SD 61","Adrian SD 61", "Adrian SD 61", "Alabama Department of Education",
"Alaska Department of Education", "Alaska Department of Education",
"Alaska Department of Education"),
SchlYr = c(2021L, 2122L, 2223L,2324L, 2021L, 2122L, 2223L,
2324L, 2324L, 2021L, 2122L, 2223L),
Total_Enrollment = c(17L, 13L, 11L, 13L, 262L, 257L, 264L,
275L, 1L, 3L, 4L, 7L),
Total_EL = c(0L, 0L, 0L, 0L, 25L, 24L, 25L, 24L, 0L, 0L, 0L, 0L),
Total_Arriver = c(0L, 0L, 0L, 0L,0L, 0L, 1L, 0L, 0L, 0L, 0L, 0L)),
row.names = c(NA, 12L), class = "data.frame")
OUTPUT <- DATA %>% group_by(InstNm) %>%
mutate(Total_Enroll_change = round(((Total_Enrollment - lag(Total_Enrollment))/ lag(Total_Enrollment))*100, 1),
Total_EL_change = round(((Total_EL - lag(Total_EL))/ lag(Total_EL))*100,1),
Total_Arriver_change = round(((Total_Arriver - lag(Total_Arriver))/ lag(Total_Arriver))*100, 1))
>Solution :
Using dplyr::across and an if_else you could do:
library(dplyr, warn = FALSE)
DATA |>
mutate(
Total_Enroll_change = round(((Total_Enrollment - lag(Total_Enrollment)) / lag(Total_Enrollment)) * 100, 1),
Total_EL_change = round(((Total_EL - lag(Total_EL)) / lag(Total_EL)) * 100, 1),
Total_Arriver_change = round(((Total_Arriver - lag(Total_Arriver)) / lag(Total_Arriver)) * 100, 1),
.by = InstNm
) |>
mutate(
across(
ends_with("_change"),
~ if_else(is.nan(.x) | is.infinite(.x), NA, .x)
)
)
