Dear r-users,
Originally my data is in notepad. I use data.frame(...) to convert the data
into columns but it has no header. The data below is what I got in R. I would
like to extract these data:
19710629 39.3 19701126
19720629 33.8 19720517
...
when I use data2_30min[1, cbind(1,3,5)] command the result is NULL.
Then I tried data2_30min[1], it gives me the whole set of data. I suspect the
data is stored in a cell.
My question is, how do I split the data from dataframe into some columns which
separating the data by spaces. Many examples given on how to split the data
with the header.
The codes and data are given below. Thank you so much for your help.
head(data_30min,10); tail(data_30min,10)
data2_30min <- data.frame(data_30min)
head(data2_30min,10); tail(data2_30min,10)
head(data_30min,10); tail(data_30min,10)
data2_30min[1]
data_30min
