The dataset includes rows representing the summary statistics for studies of type X and studies of type Y, designated by study=="Summary".study <- as.factor(c("A","B","C","A","B","Summary","Summary"))mean <- c(1.29,0.76,2.43,1.68,1.22,1.7,0.76)lowerCI <- c(0.84,0.50,1.58,1.1,0.8,1.11,0.50)upperCI <- c(1.95,1.16,3.67,2.54,1.85,2.56,1.16)type <- as.factor(c("X","X","X","Y","Y","X","Y"))df <- data.frame(study, mean, lowerCI, upperCI, type)df$study <- as.factor(df$study)I want to bold the axis tick labels for the summary effect sizes. For some reason, using an ifelse statement doesn't work when I subset. In this sample code, only the summary label for type X is bolded, whereas both should be bolded. In my real, more complex code, neither summary label is bolded. library(ggplot2)plot <- ggplot(data=df, aes(y=study, x=mean, xmin=lowerCI, xmax=upperCI, shape = type)) + geom_point(color = 'black', size=2)+ geom_errorbarh(height=.1)+ geom_point(data=subset(df,study=='Summary'), color='black', size=5)+ facet_grid(type~., scales= 'free', space='free')+ theme(axis.text.y= element_text(face=ifelse(levels(df$study)=="Summary","bold","plain")))print(plot)It appears that the culprit is the scales='free' code, because if I drop just that or change it to scales='free_x', summary is appropriately bolded twice. However, because I want to drop redundant rows for the studies that are in one subset but not the other (in this example, study C), I need this code to be included.Is there a workaround? 解决方案 You can format each instance of a given tick label across all facets using scale_y_discrete by assigning the desired labels value (including the formatting code) to a corresponding breaks value:ggplot(data=df, aes(y=study, x=mean, xmin=lowerCI, xmax=upperCI, shape = type)) + geom_point(color = 'black', size=2)+ geom_errorbarh(height=.1)+ geom_point(data=subset(df,study=='Summary'), color='black', size=5)+ facet_grid(type~., scales= 'free', space='free') + scale_y_discrete(breaks=levels(df$study), labels=c(levels(df$study)[1:3], expression(bold("Summary")))) 这篇关于有条件的ggplot中轴文本的条件格式的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云! 06-05 21:45
