周末愉快.
我一直试图复制R中这篇博客文章的结果.我正在寻找一种不使用转换数据的方法t,最好使用tidyr或reshape.在下面的示例中,metadata通过转置获得data.
metadata <- data.frame(colnames(data), t(data[1:4, ]) )
colnames(metadata) <- t(metadata[1,])
metadata <- metadata[-1,]
metadata$Multiplier <- as.numeric(metadata$Multiplier)
虽然它实现了我想要的东西,但我发现它并不那么不熟练.是否有任何有效的工作流程来转置数据框？
输入数据
data <- structure(list(Series.Description = c("Unit:", "Multiplier:",
"Currency:", "Unique Identifier: "), Nominal.Broad.Dollar.Index. = c("Index:_1997_Jan_100",
"1", NA, "H10/H10/JRXWTFB_N.M"), Nominal.Major.Currencies.Dollar.Index. = c("Index:_1973_Mar_100",
"1", NA, "H10/H10/JRXWTFN_N.M"), Nominal.Other.Important.Trading.Partners.Dollar.Index. = c("Index:_1997_Jan_100",
