df1 <- data.frame(w = 1:4, x = c("a", "b", "b", "c"), y = NA)
df1$y[df1$x == "c"] = 1
df2 <- data.frame(x = c("a", "b"), y = 1:2, z = 3:4)
我想用df2中的值更新df1以匹配行,包括所有df2列.
预期结果:
df1
w x y z
1 1 a 1 3
2 2 b 2 4
3 3 b 2 4
4 4 c 1 NA
这是我的尝试:
# add missing columns from df2 to df1
df1[setdiff(colnames(df2), colnames(df1))] <- NA
# update values in df1 from df2 for matching x
df1[df1$x %in% df2$x, colnames(df2[,-1])] <- df2[match(df1$x, df2$x),-1]
这不起作用,因为df2 [match(df1 $ x,df2 $ x), - 1]也包含不匹配.这样做的正确方法是什么？(我的实际数据帧有更多的行和列.)
EDIT1:根据请求,该示例并不代表我的实际数据的完整复杂性.在现实生活中,我正在处理df办公室(df1)和结果(df2).列"x"是"地址".
colnames(offices)
[1] "org_order" "organizations.api_path" "type"
[4] "uuid" "name" "street_1"
[7] "street_2" "postal_code_o" "city"
[10] "city_web_path" "region" "region_code2"
[13] "region_web_path" "country_o" "country_code2"
[16] "country_code3" "country_web_path" "latitude"
[19] "longitude" "created_at" "updated_at"
[22] "address" "administrative_area_level_1" "administrative_area_level_2"
[25] "country" "locality" "neighborhood"
[28] "postal_code" "route" "street_number"
colnames(results)
[1] "address" "administrative_area_level_1" "administrative_area_level_2"
[4] "country" "locality" "neighborhood"
[7] "postal_code" "route" "street_number"
[10] "subpremise" "postal_code_suffix" "premise"
[13] "political"
请注意,这是此时的图片.我希望df结果可以添加更多列(它是通过Google Maps API更新的,它根据位置返回变量字段).
EDIT2:这是来自df办公室和结果的样本数据.

这是一个完全雾化的data.table版本,用于更新两个数据集中存在的所有列,并且添加的列df2不会df1同时存在.这将更新df1到位
cols <- setdiff(colnames(df2), "x")
setDT(df1)[setDT(df2), (cols) := mget(paste0('i.', cols)), on = "x"]
df1
# w x y z
# 1: 1 a 1 3
# 2: 2 b 2 4
# 3: 3 b 2 4
# 4: 4 c 1 NA
背后的想法paste0('i.', cols)是告诉data.table,我们想从拿列data.table设在i第n定位(df2),所以它会知道如何处理,存在于两个数据集列.
