本文介绍了从更大的``查找''样式数据中查找2列的最接近值.的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个data.table(dt_1)，其中包含2列(Observed_A和Observed_B)的测量值.我需要使用这些列中的值，并在分别引用列Modeled_A和Modeled_B的样式为data.table(dt_2)的第二次查找中查找与这两列最接近的值.最终目标是，使用dt_2中具有最匹配项的行，在dt_2中选择3个其他建模列值(Variable_1，Variable_2和Variable_3)并将其添加到
I have a data.table (dt_1) that contains measured values for 2 columns (Observed_A and Observed_B). I need to use the values from those columns and lookup the nearest values to both columns in a second lookup styled data.table (dt_2) referencing columns Modeled_A and Modeled_B, respectively. The ultimate goal is to then, using the rows that have the nearest matches in dt_2, select the 3 additional modeled column values in dt_2 (Variable_1 , Variable_2 and Variable_3) and add them into dt_1.
我希望使用data.table的roll函数，因为我的实际data.tables很大(dt_1； 30列和35000行)(dt_2； 17列和15,000行)，但是我我不确定如何同时使用2列来完成此操作.
I'm hoping to use data.table's roll function as my actual data.tables are large (dt_1; 30 columns and 35000 rows) (dt_2; 17 columns and 15,000 rows) but I'm not sure how to accomplish this with 2 columns simultaneously.
以下是一些示例数据:
dt_1 <- structure(list(Observed_A = c(-9.7, -10.8, -9.7, -9.2, -9.5,
-10.1, -8.3, -7.6), Observed_B = c(-3.1, -5.2, -4.5, -4.1, -3,
-2.7, -2.6, -2.6)), class = "data.frame", row.names = c(NA, -8L))
dt_2 <- structure(list(Modeled_A = c(-6.5, -6.5, -6.5, -6.5, -6.5, -6.5,
-6.5, -6.5, -6.5, -6.5, -6.5, -6.5, -6.5, -6.5, -6.5, -6.5, -6.5,

注意:我通常不会发布这么长的示例(dt_2)，但我认为问题的本质是有根据的.
Note: I normally wouldn't post such a long example (dt_2) but I think the nature of the problem warrants it.
推荐答案
我不擅长data.table，但这是tidyverse可能会帮助您的方式-
I am not good at data.table but here's a tidyverse way that might help you -
dt_1 %>%
tibble::rownames_to_column("id") %>%
mutate(cj = 1) %>%
inner_join(dt_2 %>% mutate(cj = 1), by = "cj") %>%
select(-cj) %>%
mutate(
closeness = abs(Observed_A - Modeled_A) + abs(Observed_B - Modeled_B),
# closeness = 0 means perfect match
) %>%
arrange(id, closeness) %>%
group_by(id) %>%
slice(1) %>%
ungroup()
# A tibble: 8 x 9
id Observed_A Observed_B Modeled_A Modeled_B Variable_1 Variable_2 Variable_3 closeness
<chr> <dbl> <dbl> <dbl> <dbl> <int> <int> <int> <dbl>
1 1 - 9.70 -3.10 - 9.80 -2.80 4 448 251 0.400
2 2 -10.8 -5.20 -11.4 -5.90 80 865 63 1.30
3 3 - 9.70 -4.50 - 9.80 -4.30 37 857 281 0.300
4 4 - 9.20 -4.10 - 9.80 -4.30 37 857 281 0.800
5 5 - 9.50 -3.00 - 9.80 -2.80 4 448 251 0.500
6 6 -10.1 -2.70 - 9.80 -2.80 4 448 251 0.400
7 7 - 8.30 -2.60 - 8.20 -2.80 86 885 246 0.300
8 8 - 7.60 -2.60 - 8.20 -2.80 86 885 246 0.800
此方法避免了交叉联接，因此不应该存在内存问题.看看这是否足够快.无论哪种方式，我认为data.table都应该更快.
This method avoids the cross join so shouldn't have memory problems. See if this is fast enough for you. Either way, data.table should be faster I think.
dt_1 <- dt_1 %>%
tibble::rownames_to_column("id")
dt_2 %>%
slice(
apply(dt_1[,-1], 1, function(x) {
(abs(x[1] - dt_2$Modeled_A) + abs(x[2] - dt_2$Modeled_B)) %>%
which.min()
})
) %>%
mutate(id = as.character(1:nrow(.))) %>%
inner_join(dt_1, ., by = "id")
id Observed_A Observed_B Modeled_A Modeled_B Variable_1 Variable_2 Variable_3
1 1 -9.7 -3.1 -9.8 -2.8 4 448 251
2 2 -10.8 -5.2 -11.4 -5.9 80 865 63
3 3 -9.7 -4.5 -9.8 -4.3 37 857 281
4 4 -9.2 -4.1 -9.8 -4.3 37 857 281
5 5 -9.5 -3.0 -9.8 -2.8 4 448 251
6 6 -10.1 -2.7 -9.8 -2.8 4 448 251
7 7 -8.3 -2.6 -8.2 -2.8 86 885 246
8 8 -7.6 -2.6 -8.2 -2.8 86 885 246
