本文介绍了在R中使用逗号分隔符和指定小数格式化数字的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 29岁程序员,3月因学历无情被辞! 我想用两个千位分隔符来格式化数字,并指定小数位数。例如,我使用 format per 这为小数: FormatDecimal return(format(round(as.numeric(x),k),nsmall = k))} FormatDecimal(1000.64,1 )#1000.6 对于千位分隔符, formatC : formatC(1000.64,big.mark =,)#1,001 $ b pre $ p $ c> formatC(FormatDecimal(1000.64,1),big.mark =,)#1000.6,因为不再是数字 formatC(round(as.numeric(1000.64),1),nsmall = 1, $ 如何获得 1,000.6 ? 编辑:这个问题,询问关于格式化3.14为3,14(被标记为可能的dup) code>格式:格式: 格式(round(as.numeric(1000.64),1),nsmall = 1,big.mark =,)#1,000.6 I'd like to format numbers with both thousands separator and specifying the number of decimals. I know how to do these separately, but not together.For example, I use format per this for the decimals:FormatDecimal <- function(x, k) { return(format(round(as.numeric(x), k), nsmall=k))}FormatDecimal(1000.64, 1) # 1000.6And for thousands separator, formatC:formatC(1000.64, big.mark=",") # 1,001These don't play nicely together though:formatC(FormatDecimal(1000.64, 1), big.mark=",")# 1000.6, since no longer numericformatC(round(as.numeric(1000.64), 1), nsmall=1, big.mark=",")# Error: unused argument (nsmall=1)How can I get 1,000.6?Edit: This differs from this question which asks about formatting 3.14 as 3,14 (was flagged as possible dup). 解决方案 format not formatC:format(round(as.numeric(1000.64), 1), nsmall=1, big.mark=",") # 1,000.6 这篇关于在R中使用逗号分隔符和指定小数格式化数字的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云! 07-25 13:12
