解决了
请帮助找出以下示例可能有什么问题。
library(tidyverse)
(freq <- structure(list(Year_of_diagnosis = c(2004L, 2004L, 2005L, 2005L,
2006L, 2006L, 2007L, 2007L, 2008L, 2008L, 2009L, 2009L, 2010L,
2010L, 2011L, 2011L, 2012L, 2012L, 2013L, 2013L, 2014L, 2014L),
Sex = structure(c(1L, 2L, 1L, 2L, 1L, 2L, 1L, 2L, 1L, 2L, 1L, 2L, 1L, 2L, 1L,
2L, 1L, 2L, 1L, 2L, 1L, 2L), .Label = c("Female", "Male"), class = "factor"),
n = c(70L, 180L, 70L, 170L, 70L, 180L, 60L, 220L, 80L, 190L, 80L, 230L, 60L, 210L, 70L, 230L,
70L, 220L, 70L, 220L, 80L, 230L)),
class = c("tbl_df", "tbl", "data.frame"), .Names = c("Year", "Sex", "n"), row.names = c(NA, -22L)))
一个问题在这里：
tidyr::spread(freq, key = Sex, value = n)
它给出了以下错误：
matrixToDataFrame(x) 中的错误：找不到对象“_tibble_matrixToDataFrame”
到目前为止，我还没有更新软件包：
