包含NA的跨列求和返回NA

Question

我想对数据集中的每一行进行跨列求和。但是，列之一包含NA值。因此，新列的结果-包含列总和的结果-仅返回NA。

所需/问题列为poc.Pop。我尝试在每个列名称前添加“ sum”，并添加“ na.rm = T”，但是这不起作用。我在下面包括了可复制的代码以供参考。谢谢您的帮助！

library(dplyr)
library(plyr)

# read in data
dat <- read.csv("https://raw.githubusercontent.com/vera-institute/incarceration_trends/master/incarceration_trends.csv")

# subset data to more manageable size
dat_cali <- dat %>%
  filter(state == "CA")

# remove base dataset to free up memory
rm(dat)

# create new summed columns
dat_cali_sum <- dat_cali %>%
  mutate(poc.Inc.Pop = asian_jail_pop + black_jail_pop + latino_jail_pop + 
                               native_jail_pop + asian_prison_pop + black_prison_pop + 
                               latino_prison_pop + native_prison_pop + other_prison_pop,
         poc.Pop = asian_pop_15to64 + black_pop_15to64 + latino_pop_15to64 + 
                           native_pop_15to64 + other_pop_15to64,
         white.Inc.Pop = white_jail_pop + white_prison_pop,
         white.Pop = white_pop_15to64)

# select only relevant columns
dat_final <- dat_cali_sum %>% 
  select(year, state, county_name, poc.Inc.Pop, 
         poc.Pop, white.Inc.Pop, white.Pop)

# view problematic, broken data
View(dat_final)
