英文:
print unique values of a column next to a string sentence [using paste()]
问题
您想要的输出是：
"The following dates are present in the datetime column: 2023-04-17 13:20, 2023-04-19 16:13, 2023-04-19 16:46, 2023-04-18 09:23"
以下是代码部分的翻译：
df <- data.frame(datetime = c("2023-04-17 13:20", "2023-04-19 16:13", "2023-04-19 16:46", "2023-04-18 09:23"))
print(paste("The following dates are present in the datetime column: ",
unique(df$datetime), sep = ""))
希望这对您有所帮助。如果您需要进一步的帮助，请随时提问。
英文:
example code:
df <- data.frame(datetime = c("2023-04-17 13:20", "2023-04-19 16:13", "2023-04-19 16:46", "2023-04-18 09:23"))
print(paste("The following dates are present in the datetime column: ",
unique(df$datetime), sep = ""))
output I get:
[1] "The following dates are present in the datetime column: 2023-04-17 13:20"
[2] "The following dates are present in the datetime column: 2023-04-19 16:13"
[3] "The following dates are present in the datetime column: 2023-04-19 16:46"
[4] "The following dates are present in the datetime column: 2023-04-18 09:23"
Output I desire:
"The following dates are present in the datetime column: 2023-04-17 13:20, 2023-04-19 16:13, 2023-04-19 16:46, 2023-04-18 09:23"
I tried to create a vector of c(unique(df$datetime)), but that did not help either. Does anyone know a nice way of solving this?

你可以“双重”粘贴：
print(paste("以下日期出现在日期时间列中：",
paste(unique(df$datetime), collapse=", "), sep = ""))
[1] "以下日期出现在日期时间列中：2023-04-17 13:20, 2023-04-19 16:13, 2023-04-19 16:46, 2023-04-18 09:23"
英文:
you can "double" paste:
print(paste("The following dates are present in the datetime column: ",
paste(unique(df$datetime),collapse=", "), sep = ""))
[1] "The following dates are present in the datetime column: 2023-04-17 13:20, 2023-04-19 16:13, 2023-04-19 16:46, 2023-04-18 09:23"
