如何摆脱 geom_smooth 连续错误代码?
How do I get rid of geom_smooth continuous error code?
代码如下:
ggplot(exchangeGBP) + aes(Date, `GBP/EUR`) + geom_line(color = "deepskyblue") +
geom_smooth(method = "lm")
错误代码:
`geom_smooth()` using formula 'y ~ x'
您没有看到错误。 R 具有三种不同类型的 条件 :错误、警告和消息。以下是 Hadley Wickham 在 Advanced R 中对它们的描述(一本了解更多 R 的好书):
Fatal errors are raised by stop() and force all execution to
terminate. Errors are used when there is no way for a function to
continue.
Warnings are generated by warning() and are used to
display potential problems, such as when some elements of a vectorised
input are invalid, like log(-1:2).
Messages are generated by
message() and are used to give informative output in a way that can
easily be suppressed by the user (?suppressMessages()). I often use
messages to let the user know what value the function has chosen for
an important missing argument.
Hadley 还编写了 ggplot2 包,他的最后一句话描述了正在发生的事情。您看到的是一条消息,告诉您函数选择的公式。
在我找到解决方案之前,让我们创建一个可重现的示例。
library(ggplot2)
ggplot(mtcars, aes(x = hp, y = mpg)) +
geom_smooth()
#`geom_smooth()` using method = 'loess' and formula 'y ~ x'
有两种方法可以阻止消息出现。您可以按照书中摘录中的建议抑制消息的出现。但更好的方法是替换缺失值。在我的示例中,method 和 formula 都丢失了。您可以复制并粘贴消息中的值。
ggplot(mtcars, aes(x = hp, y = mpg)) +
geom_smooth(method = 'loess', formula = 'y ~ x')
您的示例如下所示。
ggplot(exchangeGBP) + aes(Date, `GBP/EUR`) + geom_line(color = "deepskyblue") +
geom_smooth(method = "lm", formula = 'y ~ x')
