如何从 tmap 图例输出中删除逗号?
How can I drop the comma from a tmap legend output?
我有这个代码:
tm_shape(usa, bbox = bbox, projection = map.crs)+
tm_borders(col = "grey", lwd = 1) +
tm_fill(palette = "grey") +
tm_grid(x = c(-77,-75,-73,-71),
y = c(39,37,35),
labels.inside.frame = F,
labels.size = 1.1,
col = "white") +
tm_layout(outer.margins = c(.1,.03,.05,.05),
outer.bg.color = "white")+
tm_shape(sk.dat1,axes = T) +
tm_dots("DATELAND", palette = colo,
auto.palette.mapping=FALSE,
size = .5,
breaks = seq(2010,2017,
length.out =8),legend.show = T, alpha=.7) +
tm_layout(title = "Southern Kingfish Occurrence",
legend.show = T,
legend.position = c("right","bottom"),
legend.bg.color = "grey70",
legend.height = 2)
输出这个legend。如何将 tmap 输入更改为仅包含没有逗号的单个年份?
这看起来是数字格式问题;您的代码不能完全重现,所以我不能 100% 确定,但从外观上我相当确定。
要补救,请尝试将其包含在您的 tm_layout
调用中:
legend.format=list(fun=function(x) formatC(x, digits=0, format="d"))
顺便说一下,几个月前我写了一篇关于 tmap
图例格式的简短博客 post(我的问题是货币和百分号)。
