我希望facet_wrap_paginate每個地塊Gene.Name都有單獨的地塊在串列中。有沒有辦法讓它成為一個功能？我正在使用以下代碼來創建繪圖：
tor.resp.fpkm = ggplot()
geom_bar(data = tor.responsive, aes(x = tpi, y = FPKM.Mean, fill = Genotype), stat = "identity", position = 'dodge')
scale_fill_manual(values = c("red","blue"), guide = guide_legend(title = "Genotype"))
scale_y_continuous(limit = c(NA,NA))
facet_wrap_paginate(~Gene.Name, nrow = 1, ncol = 1)
theme_prism()
theme_bw()
labs(x = "Time Post-Infestation (tpi)", y = "Mean FPKM", title = "")
theme(axis.ticks.y = element_line(color = "black")) guides(y = guide_prism_minor())
theme(plot.title = element_text(face = "bold.italic", size = 16, family = "sans", hjust = .5))
theme(axis.title.x = element_text(size = 14))
theme(axis.text.x = element_text(size = 12))
theme(axis.title.y = element_text(size = 14))
theme(axis.text.y = element_text(size = 12))
theme(legend.position = "none")
theme(panel.grid.major = element_blank(),
panel.grid.minor = element_blank(),
strip.background = element_blank(),
strip.text.x = element_blank(),
panel.border = element_rect(colour = "black", fill = NA))
theme(plot.margin = unit(c(-1.25,0.5,0.25,0.5), "cm"))
PS - 我這樣計算FPKM.Mean：
tor.responsive$FPKM.Mean = rowMeans(tor.responsive[5:7])

uj5u.com熱心網友回復：
如果您只想要一個只有一個方面的圖串列，則不必使用facet_wrap_paginate. 直接生成圖即可。作業流程如下：首先，為單個圖定義一個函式；然后，nest您的資料框基于您的組變數（Gene.Name在這種情況下）；最后，lapply或map跨每個子資料幀的繪圖函式。這是代碼。請注意，我還洗掉了ggplot代碼中一些不必要的部分。
library(ggplot2)
library(ggprism)
library(tidyr)
library(dplyr)
plotf <- function(data, title, extrema) {
extrema[[1L]] <- min(extrema[[1L]], 0)
ggplot(data)
geom_col(aes(x = tpi, y = FPKM.Mean, fill = Genotype), position = "dodge")
scale_fill_manual(values = c("S" = "red", "???" = "blue")) # You should specify colors for each value for clarity. I also noticed that you have two colors defined so there is an unknown one `???` left for you to fill in.
scale_y_continuous(limits = extrema, expand = c(0, 0)) # If you want to remove the white space left for axes limits, you should set expand = c(0, 0). It is almost certainly not recommended to set any margins to negative values.
labs(x = "Time Post-Infestation (tpi)", y = "Mean FPKM", title = title)
guides(y = guide_prism_minor())
theme_bw()
theme(
plot.title = element_text(face = "bold.italic", size = 16, family = "sans", hjust = .5),
axis.title = element_text(size = 14),
axis.text = element_text(size = 12),
axis.ticks.y = element_line(color = "black"),
panel.grid = element_blank(),
panel.border = element_rect(colour = "black", fill = NA),
plot.margin = unit(c(0,0.5,0.25,0.5), "cm"),
legend.position = "none"
)
}
tor.responsive$FPKM.Mean <- rowMeans(tor.responsive[5:7])
extrema <- range(tor.responsive$FPKM.Mean)
result <-
tor.responsive %>%
mutate(Genotype = factor(Genotype, c("S", "???"))) %>% # Don't forget to change this `???` too.
nest(data = -Gene.Name) %>%
mutate(plots = mapply(
plotf, data, Gene.Name,
MoreArgs = list(extrema = extrema), SIMPLIFY = FALSE
))
輸出
> result
# A tibble: 11 x 3
Gene.Name data plots
<chr> <list> <list>
1 MsLHCB1.1 <tibble [1 x 7]> <gg>
2 MsLHCA6 <tibble [1 x 7]> <gg>
3 MsPLGG1-A <tibble [1 x 7]> <gg>
4 MsRPI3-B <tibble [1 x 7]> <gg>
5 MsRPI1-B <tibble [1 x 7]> <gg>
6 MsPGK1 <tibble [1 x 7]> <gg>
7 MsCFBP1-A <tibble [1 x 7]> <gg>
8 MsPSBTN <tibble [1 x 7]> <gg>
9 MsTKL-1 <tibble [1 x 7]> <gg>
10 MsRCA-A <tibble [1 x 7]> <gg>
11 MsCRD1-B <tibble [1 x 7]> <gg>
然后，您可以通過result$plots[[7L]]在 R 控制臺中鍵入來訪問例如 plot 7 。情節應該是這樣的
