如何在r中

Question

打印字符串的數字我有我計算的平均值和標準差爲兩個向量和我想打印在一個單獨的行結果對於每個向量

t1<-c(37.96, 37.67, 32.29, 37.67, 38.52, 38.52, 37.67, 38.24, 36.54, 41.07, 38.81, 33.71, 37.11, 45.89) 
t2<-c(51.84, 49.57, 46.45, 50.14, 50.42, 52.4, 49, 49, 49.57, 53.54, 49.57, 46.17, 50.14, 57.22) 
mean(t1) 
sd(t1) 
mean(t2) 
sd(t2) 

結果應該是

37.97643±3.127839

50.35929±2.801649

Answer 1

你可以使用sprintf：

sprintf("%f±%f", mean(t1), sd(t1)) 
# [1] "37.976429±3.127839" 

sprintf("%f±%f", mean(t2), sd(t2)) 
# [1] "50.359286±2.801649" 

Answer 2

您還可以使用cat：

cat (mean(t1),"±",sd(t2),"\n") 
# [1] 37.97643 ± 2.801649 

cat (mean(t2),"±",sd(t2),"\n") 
# [1] 50.35929 ± 2.801649
