一、readxl读取
1、准备测试数据
2、安装、加载readxl包
install.packages("readxl") library(readxl)
3、测试
> test <- read_xlsx("test.xlsx",1) > test # A tibble: 2 x 2 a b <dbl> <dbl>
1 100 200
2 500 800
> class(test) [1] "tbl_df" "tbl" "data.frame"
> dim(test) [1] 2 2
> test2 <- read_xlsx("test.xlsx",2) > test2 # A tibble: 3 x 3 a b c <dbl> <dbl> <dbl>
1 400 200 100
2 800 900 300
3 700 600 500
> class(test2) [1] "tbl_df" "tbl" "data.frame"
> dim(test2) [1] 3 3
二、xlsx读取
> library(xlsx) ## 提前安装好这些包 > library(xlsxjars) > library(rJava) > a <- read.xlsx("test.xlsx",1,header = F) > a X1 X2 1 a b 2 100 200
3 500 800
> dim(a) [1] 3 2
> class(a) [1] "data.frame"
> b <- read.xlsx("test.xlsx",2,header = F) > b X1 X2 X3 1 a b c 2 400 200 100
3 800 900 300
4 700 600 500
> dim(b) [1] 4 3
> class(b) [1] "data.frame"
