dplyr::n函数是R语言中的一个函数,它用于计算数据框或数据集中的行数或观测数量。该函数的工作原理如下: 首先,dplyr::n函数接收一个数据框或数据集作为输入参数。 然后,它会返回该数据框或数据集中的行数或观测数量。 该函数的应用场景包括但不限于以下情况: 在数据分析和统计中,使用dplyr::n函数可以快速计算...
Today, we’ll start digging into some of the functions used to summarise data. The full summarise function will be covered for the letter S. For now, let’s look at one function from the tidyverse that can give some overall information about a dataset: n_distinct. This function counts the...

Although it is not currently possible to directly link the unique hydrolysis rate constants to biological function in the cell, these differences are likely to contribute to the higher level of complexity emerging from current studies in the Ras field. A significant population of state 1 on K-...
The GluN2 NTD-zinc interaction has profound consequences on CNS function with involvement in synaptic plasticity, pain processing and cognition38,39,40,41,42,43. Reciprocally, LBD conformational changes affect NTDs motions and binding of modulatory ligands. Therefore, the extracellular region of NMDAR...
