R 语言中的 rowMeans() 函数用于找出 DataFrame 、矩阵或数组的每一行的均值。 用法: rowMeans(data) 参数:data: DataFrame 、数组或矩阵 例子1 # R program to illustrate # rowMean function # Create example values # Set seed set.seed(1234) # Create example data data <- data.frame(matrix(round(...
在R中,可以通过设置参数na.rm为TRUE来在计算rowMeans时不包括行名。rowMeans函数用于计算数据框中每行的均值。 以下是一个示例代码: 代码语言:txt 复制 # 创建一个示例数据框 df <- data.frame(A = c(1, 2, 3), B = c(4, 5, 6), C = c(7, 8, 9)) rownames(df) <- c("Row1...
‘match.fun’ and typically is either a function or a symbol (e.g., a backquoted name) or a character string specifying a function to be searched for from the environment of the call to ‘apply’. Arguments in ‘...’ cannot have the same name as any of the other arguments, and c...
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,...
RedRabbit: DESeq2 requires R 4 and running more than a couple of releases behind in R risks multiplying problems.evodevo August 28, 2020, 12:21am 3 To add to this, I have also been using DESeq2 recently and ran into the same...
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:...
The bars, mounted at equal intervals on rigid rotatable elements, are rotatably driven to impart intermittent rearward motion of the fingers in the passageway to urge crop toward the harvesting unit.doi:US4266394 ARobert M. VanGinhovenCarl D. Brown...
R 語言中的 rowMeans() 函數用於找出 DataFrame 、矩陣或數組的每一行的均值。 用法: rowMeans(data) 參數:data: DataFrame 、數組或矩陣 例子1 # R program to illustrate # rowMean function # Create example values # Set seed set.seed(1234) # Create example data data <- data.frame(matrix(round(...
During normal operation, this offset is compensated for in a converting circuit. The required signal range of the converting circuit is consequently reduced.doi:EP0753761 B1Scott W. PetrickLawrence R. SkrenesJean C. MorvanPaul R. Granfors...
A method of monitoring forces in a planter includes measuring compressive force between contacting surfaces of the depth regulation member. The measuring may be performed with a sensor such as a piezoresistive sensor. An apparatus for monitoring force on a planter includes a sensor for measuring ...
