【问题描述】:
我想平滑我的折线图并有以下代码:
ggplot7 <- ggplot(rye) + geom_line(aes(x=date,y=ARIS_TOP), group=1, color='blue', alpha=0.5) +
geom_line(aes(x=date,y=SWI_001), group=2, color='darkturquoise', alpha=0.5) +
scale_y_continuous(limits = c(7, 27, by = 2 )) +
scale_x_date(labels = date_format('%b'), date_breaks = '2 month') +
ylab('Soil Moisture (%)')+xlab('Date') +
labs(title=('Absolute Soil Moisture')) +
stat_smooth() +
geom_hline(yintercept= c(9, 23), size =0.75, color='firebrick', linetype= 'dashed')
ggplot7 + theme_bw(base_family='Playfair', base_size = 15, base_rect_size = 1)
在线我找到了一些方法,但似乎我无法找到合适的代码。 这是我收到的错误消息:
`geom_smooth()` using method = 'loess' and formula 'y ~ x'
Fehler: stat_smooth requires the following missing aesthetics: x and y
Run `rlang::last_error()` to see where the error occurred.
【问题讨论】:
-
您能否将您正在使用的确切
geom_smooth()调用添加到示例代码中?此外,该错误会通知您在您的geom_smooth()调用中可能需要aes(x=date,y=ARIS_TOP)或aes(x=date,y=SWI_001)。 -
@teunbrand 我使用了这个代码:
geom_smooth(method = 'gam', formula = y~x, span = 1.5, )我收到的消息如下:mapping: yintercept = ~yintercept geom_hline: na.rm = FALSE stat_identity: na.rm = FALSE position_identity
