在编写字符串向量时,我们将它们放在一行中,但是我们可能想用不同的行来表示字符串,尤其是在字符串向量的每个值具有不同含义的情况下。这对程序员和其他读者都是有帮助的。我们可以使用R中的writeLines函数将单行更改为多行。
单行阅读-
> String1<-c("Covid-19","2020","Lockdown","Quarantine","Life Changing") > String1 [1] "Covid-19" "2020" "Lockdown" "Quarantine" "Life Changing"
用换行读取相同的向量-
> String1<-writeLines(c("Covid-19","2020","Lockdown","Quarantine","Life Changing")) Covid-19 2020 Lockdown Quarantine Life Changing > String2<-c("Nhooo","SIMPLY EASY LEARNING","You are browsing the best resource for Online Education","Library","Videos","Ebooks","GATE Exams", + "Coding Ground","Current Affairs","UPSC Notes","Whiteboard","Net Meeting","Tutorix") > writeLines(String2) Nhooo SIMPLY EASY LEARNING You are browsing the best resource for Online Education Library Videos Ebooks GATE Exams Coding Ground Current Affairs UPSC Notes Whiteboard Net Meeting Tutorix > String3<-c("Office","IT","Academic","Development","Business","Design","Others") > writeLines(String3) Office IT Academic Development Business Design Others > String4<-c("Machine Learning","Computer Science","Web Development","Mobile App Development","Database Management","Microsoft Technologies", + "Big Data and Analytics") > writeLines(String4) Machine Learning Computer Science Web Development Mobile App Development Database Management Microsoft Technologies Big Data and Analytics
