R批量将XPT文件，批量转成csv格式
先读取文件名，再用一个循环批量转换。
library(haven)
temp_path = list.files('./data3')
print(temp_path)
for (i in temp_path) {
# format(i)
i_temp = paste("C:/Users/BIN/Desktop/R delt/data3/",i,sep = "", collapse = NULL)
j_temp = paste("C:/Users/BIN/Desktop/R delt/data3/",i,'.csv',sep = "", collapse = NULL)
print(i_temp)
mydata <- read_xpt(i_temp)
write.csv(mydata, j_temp)
}
