我将这个文件加载到R中,然后我想计算每行1到6列的中位数,并将结果保存在一个新变量中。这会导致以下错误: Error in median.default(data[1:6], na.rm = TRUE) : need numeric data 我不确定如何解决这个问题,因为我认为所有数据都已经是数字的(除了使用na.rm =TRUE删除的na值)。请注意,为了计算平均值,...

R often recycles vectors; if it needs more elements it will go back to the start. In the example below the 1 get recycled to become length 5. > rbind(1:5, 1) [,1] [,2] [,3] [,4] [,5] [1,] 1 2 3 4 5 [2,] 1 1 1 1 1 Sometimes this is really useful, sometimes...

I have a list object in R called list_df with a length of 4 . Each 4 element contains one matrix, with one column and four rows and row names as characters. What I want to do is I would like to get means and upper and lower bounds of these means in confidence inter...
If there are no values in a range to be summed over (after removing missing values with na.rm = TRUE), that component of the output is set to 0 (*Sums) or NaN (*Means), consistent with sum and mean. See Also apply, rowsum Examples ## Compute row and column sums for a matrix:...
