在glm中用for循环使用paste（） [英] using paste() in a for loop with glm

问题描述

在下面的代码中，df.pts是一个数据框。我想运行使用不同的y变量（只有两个代码中显示）的十几个glm模型。我正在使用paste（）函数for循环，但我似乎无法使paste（）函数正常工作。我错过了paste（）？

  SPCA2 = df.pts [，3] 
 CLQU2 = df。 pts [，4] 
 
 df.list = list（SPCA2，CLQU2）
 
 for（i in df.list）{
 qp.mod = glm（粘贴（i，〜NDVI + ELEV），family =quasipoisson，data = my.data）
 print（summary（gp.mod））
} 
  

解决方案

非常感谢！主要的问题是，df.list是一个向量列表，应该是一个名称列表。

换句话说，要纠正这个问题...

pre $ $ $ $ $ $ df.list =（SPCA2，CLQU2）

而不是

  df.list = list（SPCA2，CLQU2）
  

然而，正确地指出数据帧my.data不是正确的数据框。最后，虽然没有它，但函数as.formula（）也起作用。再次，非常感谢！

In the code below, df.pts is a dataframe. I'd like to run about dozen glm models using different y variable (only two shown in the code). I'm using a for loop with the paste() function, but I can't seem to get the paste() function to work properly. What am I missing with paste()?

SPCA2 = df.pts[,3]
CLQU2 = df.pts[,4]

df.list = list(SPCA2, CLQU2)

for (i in df.list) {
    qp.mod = glm(paste(i,"~NDVI+ELEV"), family="quasipoisson", data=my.data)
    print(summary(gp.mod))
 }

解决方案

Many thanks! The main problem was that df.list was a list of vectors, and should have been a list of names.

I other words, to correct the problem...

df.list = ("SPCA2", "CLQU2")

instead of

df.list = list(SPCA2, CLQU2)

However, it was also correctly pointed out that the dataframe, my.data, was not the correct dataframe. Finally, while it worked without it, the function as.formula() also worked. Again, many thanks!
