如何修改R语言cobalt包love.plot的默认X轴标题？

Got it, let's tackle how to change the default X-axis title in love.plot() from the MatchIt package. I've dealt with this exact issue before, so here are two straightforward solutions:

方法1：直接使用love.plot()的内置参数 #

The love.plot() function actually has a built-in xlab parameter that lets you set a custom X-axis title directly. This is the simplest approach if you just need to tweak the X label:

# 修改后的代码，替换成你想要的标题
love.plot(bal.tab(Procedure~Age+Gender+NYHA, data=impdata, weights='wt'), 
          threshold = .1,
          xlab = "自定义X轴标题") # 这里替换成你的目标标题

方法2：利用ggplot2进行灵活调整 #

Since love.plot() returns a ggplot2 object by default, you can capture the plot in a variable and use ggplot2's functions to modify the X-axis title (along with other plot elements if needed):

# 先将绘图结果保存为变量
balance_plot <- love.plot(bal.tab(Procedure~Age+Gender+NYHA, data=impdata, weights='wt'), 
                          threshold = .1)

# 使用xlab()修改X轴标题
balance_plot + xlab("自定义X轴标题")

# 或者用labs()，同时调整其他标签（比如Y轴、图表标题）
balance_plot + labs(x = "自定义X轴标题",
                    y = "协变量",
                    title = "干预组与对照组协变量平衡情况")

Both methods should work perfectly—pick the one that fits your workflow best!
