mym <- matrix(1:9,nrow=3,ncol=3)

mym2 <- matrix(NA,nrow=9,ncol=1)

How about this:

```
m <- matrix(1:9, nrow=3, byrow=TRUE)
m
#> [,1] [,2] [,3]
#> [1,] 1 2 3
#> [2,] 4 5 6
#> [3,] 7 8 9
# Convert to vector by row
m2 = c(t(m))
m2
#> [1] 1 2 3 4 5 6 7 8 9
# Convert to vector by column
m3 = c(m)
m3
#> [1] 1 4 7 2 5 8 3 6 9
```

Thanks for the replying

However my data looks like this

when I use your method in R

qw<-matrix(March:April:May,nrow = 3,ncol = 51)

qw2<-matrix(March:April:May,nrow = 153,ncol=1)

qw2

qw2[1:153]<-qw

qw2

it return this

[,1]

[1,] 8568065

[2,] 8568066

[3,] 8568067

[4,] 8568068

[5,] 8568069

[6,] 8568070

[7,] 8568071

....

thanks
