First I have a matrix called stocks1:
> class(stocks1)
[1] "matrix"
Here are the first 5 rows of the last 4 columns:
> stocks1[1:5,2:5]
[,1] [,2] [,3] [,4]
[1,] 80.73 31.95 25.4 25.69
[2,] 83.66 31.95 27.12 25.2
[3,] 83.27 32.93 28.74 26.29
[4,] 83.9 34.07 29.77 26.6
[5,] 82.74 35.18 30.24 27.41
Now, why can't I convert this into a dataframe? It automatically
converts the columns into 1 long row??
> newdata.df<-data.frame(stocks1[1:5,2:5])
> newdata.df
X1.1 X1.2 X1.3 X1.4 X1.5 X1.6 X1.7 X1.8 X1.9 X1.10 X1.11 X1.12
1 80.73 83.66 83.27 83.9 82.74 31.95 31.95 32.93 34.07 35.18 25.4 27.12
X1.13 X1.14 X1.15 X1.16 X1.17 X1.18 X1.19 X1.20
1 28.74 29.77 30.24 25.69 25.2 26.29 26.6 27.41
