我想将所有数据框都以列表格式放置,以便我可以轻松地合并所有数据框,而无需键入每个数据框的名称并仅提及列表。
# importing netcdf files
files_so2 = list.files( pattern = "*.nc" )
# reading each netcdf as a dataframe
for (i in 1:length( files_so2 ) ) assign(
files_so2[i], as.data.frame(
brick( files_so2[i] ), xy = T ) )
# I want to put all the files in the list so that I can perform the following
data <- Reduce ( function(x,y) {merge( x = x, y = y , by = c("x" , "y") )} , list_data)
我在R中导入了72个数据帧,现在想将它们全部放入一个列表中,例如代码中提到的list_data来执行合并。
