2. 在NA存在的条件下直接计算p.value group<-factor(rep(c("M","C"),c(40,20))) t.test(as.numeric(test)~group) Fig 2. NA存在条件下直接计算p.value t.test(as.numeric(test)~group)$p.value,可以直接提取p-value; t.test(as.numeric(test)~group)$estimate[1], 可以直接提取相应的mean值;...
我来告诉你,那就是filter()会忽略所有缺失值,你可以看下面这个例子,仔细琢磨一下你就可以发现这个奥秘 > (df <- tibble(x = c(1,NA,3)))#不要惊慌,这个也就相当于构成一个data.frame()数据集,哎呀,差不多。不要怕 # A tibble: 3 x 1 x <dbl> 1 1. 2 NA 3 3. > filter(df,x > 1) #...
1. 数据预处理 下载数据:从公开数据库下载需要分析的数据集。 #下载数据download.data <- read.table("data.txt", header = TRUE, sep = "\t") 1. 2. 数据清洗:对数据进行处理,包括去除缺失值、标准化等。 #数据清洗cleaned.data <- na.omit(download.data) #去除缺失值 normalized.data <- scale(cl...

获取斜体的一个选项是切换到geom_bracket，使用type="expression"允许使用?plotmath表达式。关于你的第二个...
