我使用 R 中的 forestplot 包创建了一个森林图,如下所示:
own <- fpTxtGp(ticks = gpar(cex = 0.65), xlab = gpar(fontsize = 16))
xticks <- seq(from = -0.25, to = 1, by = 0.25)
fn <- local({
i = 0
no_lines <- sum(!is.na(forest$mean))
b_clrs = colorRampPalette(colors=c("#21538A", "#21538A", "#A2B6D3", "#A2B6D3", "#DAE0EC"))(no_lines)
function(..., clr.marker){
i <<- i + 1
fpDrawCircleCI(..., clr.marker = b_clrs[i])
}
})
fplot <- forestplot::forestplot(text,
fn.ci_norm = fn,
lower = forest$low,
upper = forest$high,
mean = forest$mean,
is.summary = c(TRUE, FALSE, FALSE, TRUE, FALSE, FALSE, TRUE),
xlab = "SPI-CY risk score difference (SD)",
col = fpColors(line = "darkgrey", summary = "#DAE0EC", zero = "black"),
vertices = TRUE,
grid = TRUE,
boxsize = .35,
txt_gp = own,
xticks = xticks,
lwd.zero = 1.25
)
我想直接从我的 R 笔记本中保存绘图。我通常用 ggsave 保存图,但是森林图是一个网格对象,所以这不起作用:
ggsave("forestplot.png", height = 5, width = 7, dpi = 600)
我试图用 pdf() 保存它,但这也不能直接从我的笔记本上工作。欢迎任何建议。
