10

我正在尝试创建代表重复测量的变量“波”。具体来说,我正在尝试创建表示变量 1 - 10、11 - 20 ... 91-100 的平均值的连续变量。请注意,“...”表示第 3 波到第 9 波的变量,因为避免输入这些是我的目标!

这是一个示例数据框,df有 10 行和 100 列:

mat <- matrix(runif(1000, 1, 10), ncol = 100)
df <- data.frame(mat)
dim(df)
> 10 100

dplyr::mutate一旦输入了所有变量,我就使用了which 工作,但是时间密集且容易出错。我无法找到一种方法来这样做,而无需手动输入列的名称,正如我在下面开始做的那样(注意“...”代表第 3 波到第 9 波):

df <- df %>% 
      mutate(wave_1 = (X1 + X2 + X3 + X4 + X5 + X6 + X7 + X8 + X9 + X10) / 10,
             wave_2 = (X11 + X12 + X13 + X14 + X15 + X16 + X17 + X18 + X19 + X20) / 10,
             ...
             wave_10 = (X91 + X92 + X93 + X94 + X95 + X96 + X97 + X98 + X99 + X100) / 10)

您可以 mutate使用“dplyr”进行多个/连续列吗?也欢迎其他方法。

这是包装的一种方式zoo

library(zoo)
t(rollapply(t(df), width = 10, by = 10, function(x) sum(x)/10))

这是使用基础 R 的一种方法:

splits <- 1:100
dim(splits) <- c(10, 10)
splits <- split(splits, col(splits))
results <- do.call("cbind", lapply(splits, function(x) data.frame(rowSums(df[,x] / 10))))
names(results) <- paste0("wave_", 1:10)
results

另一种非常简洁的方式使用基础 R(由 G.Grothendieck 提供):

t(apply(df, 1, tapply, gl(10, 10), mean))

这是一个解决方案dplyrand tidyr

library(dplyr)
library(tidyr)
df$row <- 1:nrow(df)
df2 <- df %>% gather(column, value, -row)
df2$column <- cut(as.numeric(gsub("X", "", df2$column)),breaks = c(0:10*10))
df2 <- df2 %>% group_by(row, column) %>% summarise(value = sum(value)/10)
df2 %>% spread(column, value) %>% select(-row)

另一种dplyr解决方案更接近 OP 指示的语法并且不需要重铸数据帧。

4 波计算以略微不同但矢量化(即rowSumsrowMeans)的方式做基本相同的事情:

df <- df %>% 
      mutate(wave_1 = rowSums(select(., num_range("X", 1:10)))/10,
             wave_2 = rowSums(select(., c(11:20)))/10,
             wave_3 = rowMeans(select(., X21:X30)),
             wave_4 = rowMeans(.[, 31:40]))

编辑:.可用作当前数据帧的占位符df(代码已相应更改)。还添加了 wave_4 以证明它可以像数据框一样使用。

如果操作函数不是向量化的(即不能在整个数据帧上使用,例如),rowSums也可以使用非向量化函数(例如rowwisedomyfun

myfun <- function (x) {
  sum(x)/10
}

tmp=df %>%
  rowwise() %>%
  do(data.frame(., wave_1 = myfun(unlist(.)[1:10]))) %>%
  do(data.frame(., wave_2 = myfun(unlist(.)[11:20])))

注意:.更改似乎改变了它的含义,指的是整个数据框,mutate但仅指do.

我们也可以这样做purrr::map2

library(purrr)

set.seed(123)
mat <- matrix(runif(1000, 1, 10), ncol = 100)
df <- data.frame(mat)

data.frame(from = seq(10, 100, 10) - 9, 
           to = seq(10, 100, 10)) %>%
  {map2_dfc(.$from, .$to, ~ rowMeans(df[, .x:.y]))} %>%
  set_names(paste0("Wave_", seq_along(.)))

# A tibble: 10 x 10

基础 R中,我们也可以这样做:

tmp <- split.default(df, ceiling(seq_along(df) / 10))  

as.data.frame(Reduce(function(x, y) {
  cbind(x, rowMeans(tmp[[y]]))
}, 2:length(tmp), init = rowMeans(tmp[[1]]))) |>

使用的另一种方法(以及 IMO 推荐的方法)是在汇总每个波的值之前首先将dplyr您的数据重塑或融合为整洁的数据格式。

详细地说,这个过程将涉及:

  1. 将数据重塑为长格式 ( tidyr::gather)
  2. 确定哪些变量属于每个“波”
  3. 汇总每个波的值
  4. 将数据重新整形为宽格式 ( tidyr::spread)

在您的示例中,这将如下所示:

library(tidyverse)

mat <- matrix(runif(1000, 1, 10), ncol = 100)
df <- data.frame(mat)
dim(df)

df %>%
  dplyr::mutate(id = dplyr::row_number()) %>%
  # reshape to "tidy data" or long format
  tidyr::gather(varname, value, -id) %>%
  # identify which variables belong to which "wave"
  dplyr::mutate(varnum = as.integer(stringr::str_extract(varname, pattern = '\\d+')),
                wave = floor((varnum-1)/10)+1) %>%
  # summarize your value for each wave
  dplyr::group_by(id, wave) %>%
  dplyr::summarise(avg = sum(value)/n()) %>%
  # reshape back to "wide" format
  tidyr::spread(wave, avg, sep='_') %>%
  dplyr::ungroup()

使用以下输出:

# A tibble: 10 x 11
      id wave_1 wave_2 wave_3 wave_4 wave_5 wave_6 wave_7 wave_8 wave_9 wave_10
   <int>  <dbl>  <dbl>  <dbl>  <dbl>  <dbl>  <dbl>  <dbl>  <dbl>  <dbl>   <dbl>
 1     1   6.24   4.49   5.85   5.43   5.98   6.04   4.83   6.92   5.43    5.52
 2     2   5.16   6.82   5.76   6.66   6.21   5.41   4.58   5.06   5.81    6.93
 3     3   7.23   6.28   5.40   5.70   5.13   6.27   5.55   5.84   6.74    5.94
 4     4   5.27   4.79   4.39   6.85   5.31   6.01   6.15   3.31   5.73    5.63
 5     5   6.48   5.16   5.20   4.71   5.87   4.44   6.40   5.00   5.90    3.78
 6     6   4.18   4.64   5.49   5.47   5.75   6.35   4.34   5.66   5.34    6.57
 7     7   4.97   4.09   6.17   5.78   5.87   6.47   4.96   4.39   5.99    5.35
 8     8   5.50   7.21   5.43   5.15   4.56   5.00   4.86   5.72   6.41    5.65
 9     9   5.27   5.71   5.23   5.44   5.12   5.40   5.38   6.05   5.41    5.30
10    10   5.95   4.58   6.52   5.46   7.63   5.56   5.82   7.03   5.68    5.38

这可以连接回您的原始数据以匹配您给出的示例(使用mutate),如下所示:

df %>%
  dplyr::mutate(id = dplyr::row_number()) %>%
  tidyr::gather(varname, value, -id) %>%
  dplyr::mutate(varnum = as.integer(stringr::str_extract(varname, pattern = '\\d+')),
                wave = floor((varnum-1)/10)+1) %>%
  dplyr::group_by(id, wave) %>%
  dplyr::summarise(avg = sum(value)/n()) %>%
  tidyr::spread(wave, avg, sep='_') %>%
  dplyr::ungroup() %>%
  dplyr::right_join(df %>%    # <-- join back to original data
                     dplyr::mutate(id = dplyr::row_number()),
                   by = 'id')

这种方法的一个很好的方面是您可以检查数据以确认您正确地将变量分配给“wave”。

df %>%
  dplyr::mutate(id = dplyr::row_number()) %>%
  tidyr::gather(varname, value, -id) %>%
  dplyr::mutate(varnum = as.integer(stringr::str_extract(varname, pattern = '\\d+')),
                wave = floor((varnum-1)/10)+1) %>%
  dplyr::distinct(varname, varnum, wave) %>%
  head()

产生:

  varname varnum wave
1      X1      1    1
2      X2      2    1
3      X3      3    1
4      X4      4    1
5      X5      5    1
6      X6      6    1
