问题描述
对不起，如果这是非常基本的.我有一个名称列表和一个以这些名称作为列名称的矩阵.但是，姓氏的顺序不同.
Sorry if this is very basic. I have a list of names and a matrix with those names as column names. However, the colnames are in a different order.
例如.名称列表:colname4 colname3 colname2 colname5 colname1矩阵姓氏:colname1 colname2 colname3 colname4 colname5
Eg. List of names: colname4 colname3 colname2 colname5 colname1Matrix Colnames: colname1 colname2 colname3 colname4 colname5
我试图按与名称列表顺序相同的顺序对矩阵列进行排序.
I am trying to order the matrix columns in the same order as list of names order.
我尝试了test <- match(colnames(matrix1), colnames(matrix2))，但没有成功.你知道其他办法吗?
I have tried test <- match(colnames(matrix1), colnames(matrix2)) but it didn't work. Do you know any alternative?
推荐答案
您只需使用向量来命名名称和[-运算符，如下所示:
You just have to use a vector for the names and the [-operator as follows:
col.order <- c("colname4","colname3","colname2","colname5","colname1")
M[,col.order]
