更改此图中的顺序[重复]

Question

我有这个数据和代码，我有这个情节

在情节中，您会看到无响应者先来，然后响应者来

在代码中我看不到如何更改组

                                                                                                                                                                                                                                          "Non-responders")), row.names = c(NA, -22L), class = "data.frame")
library(dplyr)
library(ggplot2)
library(ggrepel)

x <- x %>%
  rename(log10_qvalue = log10_pvalue)

ggplot(data = x, aes(x = log10_qvalue, y = Percentage_altered/100, color = CNV)) +
  geom_point( ) +
  scale_discrete_manual(aesthetics = "colour", values = c("Deletion" = "blue", "Amplification" = "red")) +
  geom_text_repel(aes(label = gene), size = 5) +
  facet_grid(CNV ~ group) +
  labs(x = "-log10(qvalue)", y = "Net frequency of gain and deletion (%)") +
  theme_bw() +
  theme(
    legend.position = "none",
    axis.title = element_text(size = 12, face = "bold"),
    axis.text = element_text(size = 12, face = "bold"),
    strip.text = element_text(size = 12, face = "bold")
  )

如何更改此代码以使第一响应者进入左侧，非响应者进入右侧？

将组更改为“因素”。这样顺序是由因子中的顺序而不是字母顺序定义的。

x$group <- factor(x$group, levels = c("Responders", "Non-responders"))
