Grothendieck's answer to "last name, first name" -> "first name last name" in serialized strings to get to gsub("([^ ]*) ([^ ]*)", "\\2, \\1", str) which gives me - Obama, Barack J., DonaldTrump, Edgar, J.Hoover, Knowles-Carter, Beyonce Sting What I would like to get - Obama, Barack Trump, Donald J.

问题 I am trying to remove all the Chinese characters from the following string: x <- "2.87Y 1282501 12电网MTN4 AAA 4.40 /4.30* 2000、" How can I do this? 回答1: I went Googling around and found a page about Unicode character ranges. After looking through some of the CJK (Chinese, Japanese, Korean) Unicode ranges, I came to the conclusion that you need to remove the following Unicode ranges if all your strings are similar to this particular string. 4E00-9FFF for CJK Unified Ideographs 3000-303F for CJK

问题 When plotting a bar chart, I often add labels to bars to signify the y-value for each bar. However, I run into trouble when the bar becomes too low, making the label unreadable or simply ugly. Example library(ggplot2) df_blood <- data.frame(blood_type = c("O-", "O+", "A-", "A+", "B-", "B+", "AB-", "AB+"), frequency = c(0.13, 0.35, 0.08, 0.3, 0.02, 0.08, 0.01, 0.02)) ggplot(df_blood, aes(x = blood_type, y = frequency, fill = blood_type)) + geom_bar(stat = "identity") + geom_text(aes(label =
