介绍绘制的校准曲线使用geom_errorbar():格式化数据以GGPLOT2
我有汇总统计的针对三个不同的空气质量测量一个数据帧。仪器名称为aa34
,aa35
和48c
。它们各自以ppm为单位测量一氧化碳。我有广泛格式的数据,其中每个向量是三种仪器中的每一种的均值,标准差,标准误差或95%置信区间。
我想用绘制和ggplot()
这些geom_errorbar()
汇总统计,但我有一些麻烦的数据为长格式和ggplot()
提供颜色映射的ID变量。我正在关注this教程。下面是我想重现的数字(当然,用有毒气体取代豚鼠的牙齿数据)。我试图添加一个额外的y变量,并让它们通过ID
变量进行颜色协调。我期望的输出将用示例中的supp
向量替换三个id
向量中的两个,即包含aa34
和aa35
的向量。我相当于dose
载体将是ref.co.mean
,我们的x
变量。我相当于len
矢量将是长格式的矢量aa34.co.mean
和aa35.co.mean
。

提前致谢!
您可以编辑您的问题,包括'dput(df_cal)的输出',使这个容易复制? –
此外,我想知道你在哪里计算你的汇总统计?它是“Excel”吗?使用'Rmisc'包中的'SummarySE'函数可以让你更容易,就像你的示例链接一样。 –
@ J.Con感谢'dput()'提示。这不太好,但是如果你复制并粘贴到控制台中,它似乎就可以工作。我仍然使用'R'来计算我的汇总统计。我用'dplyr'从7个时间序列中手动过滤出“高原”。然后,我使用一些基本功能为7个步骤中的每个步骤中的三个仪器中的每一个生成标准偏差,标准误差和95%置信区间的向量。然后,我在7个校准步骤中的每一个上执行'row_bind()',然后是每个校准步骤仅提供一次观察的'unique()'。 – spacedSparking
