我对R比较陌生,我正在努力解决与qqplot
相关的错误消息。一些样本数据位于底部。我试图在一些方位角数据上做一个qqplot
,比如指南针方向。我在这里和?qqplot
R文档一起环顾四周,但我没有看到我能理解的解决方案。我不理解函数的语法或数据应该是的格式,或者可能两者都有。我首先尝试将数据加载为单列值,即只是“方位角”列。
azimuth <- read.csv(file.choose(), header=TRUE)
qqplot(azimuth$Azimuth)
返回以下错误,
Error in sort(y) : argument "y" is missing, with no default
然后我尝试将相应的倾角与方位角数据一起包括在内并收到相同的误差。我也试过了,
qqnorm(azimuth)
但是这返回了以下错误,
Error in xy.coords(x, y, xlabel, ylabel, log) :
'x' and 'y' lengths differ
数据帧“方位角”:

似乎qqplot
函数有两个输入参数,x
和y
如下:
qqplot(x, y, plot.it = TRUE, xlab = "your x-axis label", ylab="your y-axis label", ...)
当你按照上面的说法打电话时,你只给了一个向量,因此R抱怨y
参数丢失了。检查您输入的数据集,看看您是否可以找到x
和y
用于调用qqplot
的内容。
也许你想创建图表。
你尝试过吗?
qqnorm(azimuth$Azimuth);qqline(azimuth$Azimuth)
尝试:
qqPlot
与首都P
