Qualtrics 生成 csv 文件,第一行包含变量名称,第二行包含变量标签。我想使用 read_csv() 读取我的数据,同时将第一行作为列名读取,然后跳过下一行变量标签。以下是我失败的尝试。
library(readr)
mydata <- read_csv("qualtrics_data.csv", col_names = TRUE, skip = 2) # this would actually skip both the names and label rows.
你可以只读两次——一次是为了获取名字,然后是为了获取数据。
library(readr)
library(dplyr)
csv_file <- "mpg,cyl,disp,hp,drat,wt
mpg,cyl,disp,hp,drat,wt
21.0,6,160,110,3.90,2.875
22.8,4,108,93,3.85,2.320
21.4,6,258,110,3.08,3.215
18.7,8,360,175,3.15,3.440
18.1,6,225,105,2.76,3.460"
df_names <- read_csv(csv_file, n_max = 0) %>% names()
df_names
#> [1] "mpg" "cyl" "disp" "hp" "drat" "wt"
df <- read_csv(csv_file, col_names = df_names, skip = 2)
df
#> # A tibble: 5 x 6
#> mpg cyl disp hp drat wt
#> <dbl> <int> <int> <int> <dbl> <dbl>
#> 1 21.0 6 160 110 3.90 2.875
#> 2 22.8 4 108 93 3.85 2.320
#> 3 21.4 6 258 110 3.08 3.215
#> 4 18.7 8 360 175 3.15 3.440
#> 5 18.1 6 225 105 2.76 3.460
使用read.csv
例如:
df <- read.csv("example.csv")
df <- df[-1,] # -1 removes the first row, you can change to -2 to remove 2nd row...etc
