r - 代码逐行运行良好,但在 rmarkdown 中作为一个整体运行时失败
问题描述
当我只运行这行代码时,结果符合预期。当我运行块时,突变在第三行停止。我该如何解决这个问题,我觉得这是我以前用相同的代码没有遇到过的新东西。
样本数据:
> dput(head(out))
structure(list(SectionCut = c("S-1", "S-1", "S-1", "S-1", "S-2",
"S-2"), OutputCase = c("LL-1", "LL-2", "LL-3", "LL-4", "LL-1",
"LL-2"), V2 = c(81.782, 119.251, 119.924, 96.282, 72.503, 109.595
), M3 = c("-29.292000000000002", "-32.661999999999999", "-30.904",
"-23.632999999999999", "29.619", "32.994"), id = c("./100-12-S01.xlsx",
"./100-12-S01.xlsx", "./100-12-S01.xlsx", "./100-12-S01.xlsx",
"./100-12-S01.xlsx", "./100-12-S01.xlsx")), row.names = c(NA,
-6L), class = c("grouped_df", "tbl_df", "tbl", "data.frame"), groups = structure(list(
SectionCut = c("S-1", "S-1", "S-1", "S-1", "S-2", "S-2"),
OutputCase = c("LL-1", "LL-2", "LL-3", "LL-4", "LL-1", "LL-2"
), id = c("./100-12-S01.xlsx", "./100-12-S01.xlsx", "./100-12-S01.xlsx",
"./100-12-S01.xlsx", "./100-12-S01.xlsx", "./100-12-S01.xlsx"
), .rows = list(1L, 2L, 3L, 4L, 5L, 6L)), row.names = c(NA,
-6L), class = c("tbl_df", "tbl", "data.frame"), .drop = TRUE))
> dput(head(Beamline_Shear))
structure(list(VLL = c(159.512186, 154.3336, 149.4451613, 167.0207595,
161.2269091, 156.4116505)), row.names = c("84-9", "84-12", "84-15",
"92-9", "92-12", "92-15"), class = "data.frame")
我试图运行的代码:
Shear <- out[,-4] %>% mutate(N_l = str_extract(OutputCase,"\\d+"),
UG = str_extract(id,"\\d+"), a = str_extract(id,"-\\d+"),
S = str_extract(a,"\\d+"), Sections = paste0(UG,"-",S),
Sample = str_remove_all(id, "./\\d+-\\d+-|.xlsx")) %>%
left_join(Beamline_Shear %>% rownames_to_column("Sections"), by = "Sections") %>%
select(-OutputCase,-id,-Sections,-a)
解决方案
数据中有一些组属性应该可以正常工作,但如果我们在不同的环境中运行,则可能会出现问题。此外,mutate
步骤和连接步骤实际上并不需要任何分组属性,因为它们是非常简单的矢量化行操作。
library(dplyr)
out %>%
select(-4) %>%
ungroup %>% # // removes group attributes
mutate(N_l = str_extract(OutputCase,"\\d+"),
UG = str_extract(id,"\\d+"), a = str_extract(id,"-\\d+"),
S = str_extract(a,"\\d+"), Sections = paste0(UG,"-",S),
Sample = str_remove_all(id, "./\\d+-\\d+-|.xlsx")) %>% left_join(Beamline_Shear %>% rownames_to_column("Sections"), by = "Sections")
# A tibble: 6 x 11
