R FUN(X[[i]],…)中的错误:对象';a';找不到
我试图绘制两个变量之间的关系——用点回归线表示。我还想在此图上添加两个灰色面板,如下图所示 几天前我写了代码,它工作得很好。但突然间,我开始在最后一步收到错误消息“error in FUN(X[[I]],…):object'a'not found”,并且它正在添加灰色面板。我在谷歌上搜索这个问题,尝试更新软件包,然后重新启动它。这些似乎都不管用。 以下是代码和输出,供您参考R FUN(X[[i]],…)中的错误:对象';a';找不到,r,ggplot2,R,Ggplot2,我试图绘制两个变量之间的关系——用点回归线表示。我还想在此图上添加两个灰色面板,如下图所示 几天前我写了代码,它工作得很好。但突然间,我开始在最后一步收到错误消息“error in FUN(X[[I]],…):object'a'not found”,并且它正在添加灰色面板。我在谷歌上搜索这个问题,尝试更新软件包,然后重新启动它。这些似乎都不管用。 以下是代码和输出,供您参考 > # read files > > tpreg1=read.csv("tpreg1.csv", he

FUN(X[[i]],…)中出错:未找到对象“a”
有人能帮我找到解决办法吗?提前感谢。在您的首字母
ggplot()
中,您指定y=a
。此映射将被转发,直到被覆盖。出现错误时,您指定的数据不包含a
,但a
仍映射到y
。尝试显式设置y=NULL
以覆盖映射。正如@mnist所解释的,美学是从ggplot()
中的初始绘图规范继承而来的
更干净的解决方案是在geom_ribbon()
的后续层中将默认的inherit.aes=TRUE
改为FALSE
,即:
> tpr <- tpr +
+ geom_ribbon(
+ data = tpreg3,
+ aes(x = t, ymin = func1, ymax = func2),
+ fill = "grey",
+ alpha = .25,
+ inherit.aes = FALSE
+ ) +
>tpr非常感谢@mnist,它成功了!我试图了解更多关于这类错误的信息,但无法轻松阅读。你能推荐任何能为这种错误提供简单解释的链接吗。
