Dear R helpers
I have a data frame as given below
df = data.frame(A = c(776,827,836,995,855,1026,1203,1363,965,1195),
B = c(806,953,1049,1056,1243,764,1148,1162,948,1154),
C = c(959,1155,1193,1163,863,1070,1087,877,1132,944),
D = c(906,760,978,1170,1009,883,1007,960,828,113))
# Actually the real data has number of vectors and not only A, B, C and D.
m = as.numeric(lapply(df, mean))
s = as.numeric(lapply(df, sd))
gives
> m
[1] 1004.1 1028.3 1044.3 861.4
> s
[1] 194.5899 158.7052 123.3000 285.8695
I need to generate 25 (normal) random numbers for each of these mean and
corresponding standard deviation combination (m[i], s[i]). i.e. I need to have
a table (dim 25 X 4) giving me random numbers.
rnorm(25, m[1], s[1]) rnorm(25, m[2], s[2]) rnorm(25, m[3], s[3])
rnorm(25, m[4], s[4])
