[英]How to perform Tukey's pairwise test in R?
I have the following data (dat) 我有以下数据(日期)
I have the following data(dat) 我有以下数据(日期)
V W X Y Z
1 8 89 3 900
1 8 100 2 800
0 9 333 4 980
0 9 560 1 999
I wish to perform TukeysHSD pairwise test to the above data set. 我希望对上述数据集执行TukeysHSD成对测试。
library(reshape2)
dat1 <- gather(dat) #convert to long form
pairwise.t.test(dat1$key, dat1$value, p.adj = "holm")
However, every time I try to run it, it keeps running and does not yield an output. 但是,每次我尝试运行它时,它都会继续运行,并且不会产生输出。 Any suggestions on how to correct this?
关于如何纠正这一点的任何建议?
I would also like to perform the same test using the function TukeyHSD(). 我还想使用功能TukeyHSD()执行相同的测试。 However, when I try to use the wide/long format, I run into a error that says
但是,当我尝试使用宽/长格式时,我遇到了一个错误,指出
" Error in UseMethod("TukeyHSD") :
no applicable method for 'TukeyHSD' applied to an object of class "data.frame"
We need 'x' to be dat1$value as it is not specified the first argument is taken as 'x' and second as 'g' 我们需要将'x'设为dat1 $ value,因为未指定第一个参数为'x',第二个参数为'g'
pairwise.t.test( dat1$value, dat1$key, p.adj = "holm")
#data: dat1$value and dat1$key
# V W X Y
#W 1.000 - - -
#X 0.018 0.018 - -
#Y 1.000 1.000 0.018 -
#Z 4.1e-08 4.1e-08 2.8e-06 4.1e-08
#P value adjustment method: holm
Or we specify the argument and use in any order we wanted 或者我们指定参数并以我们想要的任何顺序使用
pairwise.t.test(g = dat1$key, x= dat1$value, p.adj = "holm")
Regarding the TukeyHSD
关于
TukeyHSD
TukeyHSD(aov(value~key, data = dat1), ordered = TRUE)
#Tukey multiple comparisons of means
# 95% family-wise confidence level
# factor levels have been ordered
#Fit: aov(formula = value ~ key, data = dat1)
#$key
# diff lwr upr p adj
