paste(month.abb, "is the", nth, "month of the year.", sep = "_*_") ## To collapse the output into a single string, pass a collapse argument. paste0(nth, collapse = ", ") ## For inputs of length 1, use the sep argument rather than collapse paste("1st", "2nd", "3rd",...
R语言cat函数、cat函数基于特定分割符(separator)将向量内容连接起来形成新的字符串、cat函数基于labels参数和paste函数为向量vector的输出内容添加标签、设置file参数将cat函数拼接后的内容输出到指定目录文件…

pattern matching, or other similar stringr package functions. Let’s start with the base case – using paste() to convert avector of values into a string. This takes independent
paste0(..., collapse = NULL, recycle0 = FALSE) 1. 2. 举例: ## When passing a single vector, paste0 and paste work like as.character. > paste(1:12) [1] "1" "2" "3" "4" "5" "6" "7" "8" "9" "10" "11" "12" ...
