过滤等于或大于特定值的数据的功能 [英] Function to filter data equal to or greater than a certain value

问题描述

我有一个包含数千行和列的数据框.行包含基因名称，列包含样品名称.

I have a dataframe containing thousands of rows and columns. The rows contain the names of genes and the columns the names of samples.

我只想在3个以上的样本中保留包含等于或大于5的值的行.

I only want to keep the rows that contain a value equal to or greater than 5 in more than 3 samples.

到目前为止，我已经尝试过了，但是我不知道如何设置多个条件:

I tried this so far but I can't figure out how to set multiple conditions:

data.frame1 %>% filter_all(all_vars(.>= 5))

我希望我已经正确回答了这个问题.

I hope I have stated this question correctly.

推荐答案

在基因表达过滤前的差异基因表达管道中的处理方式如下:

The way I do it in my gene expression filtering pre-differential gene expression pipeline is as follows:

data.frame1[rowSums(data.frame1 >= 5) > 3, ] -> filtered.counts

如果第一列是您的基因标识符，而其他所有列都是数字，则可以使评估跳过第一列，如下所示:

And if your first column is your gene identifier, with all the other columns being numeric, you can have the evaluation skip the first column as follows:

data.frame1[rowSums(data.frame1[-1] >= 5) > 3, ] -> filtered.counts
