对 R 中的不同数据帧应用相同的操作

Question

I am trying to apply same functions to several data frames. My data looks like this. I have several data frames for different years. I want to get rid of year specific names in order to merge data frames into one.

ID	educ_1995	year_1995
k1	0	1995
k2	1	1995
k3	0	1995

I have tried following:

files <- list(workers_1995, workers_1996)
files <- lapply(files, function)
# I tried to make a list of my data frames and then write a function for them. 


myfunc <- function(files){
  files %>% 
    rename(igang=starts_with("igang")) %>% 
    rename(year=starts_with("year")) 
}

I would like to get the results in form of same tibbles, but with changed names.

Answer 1

Change the order and place myfunc inside the parentheses:

files <- list(workers_1995, workers_1996)

myfunc <- function(onefile){
  onefile %>% 
    rename(igang=starts_with("igang")) %>% 
    rename(year=starts_with("year")) 
}

lapply(files, myfunc)
