从数据框MyData中的变量VAR中删除属性ATT:
to remove the attribute ATT from variable VAR in your data-frame MyData:
attr(MyData$VAR, "ATT") <- NULL
如果要删除所有变量的几个属性:
If you want to remove several attributes of all variables :
For (var in colnames(MyData)) {
attr(MyData[,deparse(as.name(var))], "ATT_1") <- NULL
attr(MyData[,deparse(as.name(var))], "ATT_2") <- NULL
}
