R语言filein R语言filter函数编写MA(q)模型 一 移动平均 移动平均能消除数据中的季节变动和不规则变动。若序列中存在周期变动,则通常以周期为移动平均项数。移动平均法可以通过数据显示出数据长期趋势的变动规律。 R可用filter()函数做移动平均。用法:filter(data,filter,sides) 1、简单移动平均 简单移动平均就是将n...
在R中使用dplyr包的filter函数可以根据条件筛选数据。filter函数可以用于数据框或数据表中,根据指定的条件选择满足条件的行。 使用filter函数的语法如下: 代码语言:R 复制 filtered_data <- filter(data, condition) 其中,data是要筛选的数据框或数据表,condition是一个逻辑表达式,用于指定筛选条件。 例如,如果我们有...
