我一直在使用包waffle,我无法解决如何修复这个华夫饼图,使它显示100个平方/单元格

这是数据和我的代码:
# devtools::install_github("hrbrmstr/waffle")
library(ggplot)
library(waffle)
data <- structure(list(greenfield = c(0, 1), n = c(162L, 399L), total_investments = c(561,
561), percentage = c(28.8770053475936, 71.1229946524064), name_greenfield = c("M&A",
"Greenfield")), row.names = c(NA, -2L), groups = structure(list(
greenfield = c(0, 1), .rows = structure(list(1L, 2L), ptype = integer(0), class = c("vctrs_list_of",
"vctrs_vctr", "list"))), row.names = c(NA, -2L), class = c("tbl_df",
"tbl", "data.frame"), .drop = TRUE), class = c("grouped_df",
"tbl_df", "tbl", "data.frame"))
# Waffle plot
ggplot(data,
aes(fill = name_greenfield,
values = percentage)) +
coord_equal() +
geom_waffle(size = 0.31,
flip = T,
make_proportional = T,
height = 0.9, width = 0.9,
color = "white") +
coord_equal() +
theme_ipsum_rc(grid="",
plot_title_face = "plain",
plot_title_size = 14,
plot_title_margin = 0) +
theme_enhance_waffle() +
labs(title = "Types of investments",
fill = "",
caption = "Source: Author's own elaboration") +
scale_fill_grey(start = 0.4, end = 0.7)我还没有发现问题,如果有人能帮我的话,我会很感激的!

代码中有一个非常非常奇怪的错误。我怀疑这是怎么回事。在GitHub的源代码中,有一个文件stat-waffle.R。在第93行,您会发现:
if (params[["make_proportional"]]) {
.x[["values"]] <- .x[["values"]] / sum(.x[["values"]])
.x[["values"]] <- round_preserve_sum(.x[["values"]], digits = 2)
.x[["values"]] <- as.integer(.x[["values"]] * 100)
}有些奇怪的事情发生在你的价值观上。
.x <- list(values = c(29, 71))
.x[["values"]] <- .x[["values"]] / sum(.x[["values"]])
# [1] 0.29 0.71
.x[["values"]] <- waffle:::round_preserve_sum(.x[["values"]], digits = 2)
# [1] 0.29 0.71
.x[["values"]] <- as.integer(.x[["values"]] * 100)
# [1] 28 71这就是为什么你看到一个丢失的广场。这和浮点数的数学有关。
format(round(.x$values / sum(.x$values), 2) * 100, digits = 22)
# [1] "28.999999999999996" "71.000000000000000"如果您进行此修改,结果将如预期的那样。
.x[["values"]] <- as.integer(round(.x[["values"]] * 100))
# [1] 29 71这对你意味着什么?将数字四舍五入为整数,提前加到100,并使用make_proportional = FALSE。这样,代码块就不会运行。
data$percentage <- as.integer(round(round(data$percentage / sum(data$percentage), 2) * 100))
data$percentage
# [1] 29 71
ggplot(data,
aes(fill = name_greenfield,
values = percentage)) +
coord_equal() +
geom_waffle(size = 0.31,
flip = T,
make_proportional = FALSE,
height = 0.9, width = 0.9,
color = "white") +
coord_equal() +
theme_enhance_waffle() +
labs(title = "Types of investments",
fill = "",
caption = "Source: Author's own elaboration") +
scale_fill_grey(start = 0.4, end = 0.7)这应该能给你带来你所期待的。
