I have a dataframe ddata where the variable Location has the Latitude and Longitude in string format separated by a comma. So when I type ddata$Location into my console I see this:

"33.9829, -118.3338"
"34.0454, -118.3157"
"33.942,  -118.2717"
"33.9572, -118.2717"

How do I separate this column by the comma, a delimiter, and get it to become 2 columns called: Longitude and Latitude? I have tried the split function but cannot get it to work.


As it is separated by ,, the easiest option is read.csv (assuming that the class of 'Location' is character and not factor. If it is factor, convert it to character (with as.character(ddata$Location))

out <- read.csv(text = ddata$Location, header = FALSE,
      col.names = c("Latitude", "Longitude"))

Now, we cbind it with the original data

ddataNew <- cbind(dddata, out)

Splitting a dataframe string column into multiple different columns , A very direct way is to just use read.table on your character vector: > read.table(​text = text, sep = ".", colClasses = "character") V1 V2 V3 V4 1 F US CLE V13 2 F  I am having two columns (A and B) in my data frame. In each of the rows for columns A and B, there is a string of numbers separated by commas. Row 1, Column A - 1,2,3,4. Row 1, Colummn B - 5,6,7,8. I want to combine the values and create another Column C so that output looks like: Row 1, Column C - 6,8,10,12


You can use the str_split_fixed function in the stringr package, like this:

library(stringr)
ddata[,c("Longitude", "Latitude")] <- str_split_fixed(ddata$Location, ", ", 2)

It will give you:

#             Location  Longitude   Latitude
# 1 33.9829, -118.3338    33.9829  -118.3338
# 2 34.0454, -118.3157    34.0454  -118.3157
# 3  33.942, -118.2717     33.942  -118.2717
# 4 33.9572, -118.2717    33.9572  -118.2717

Then, if you want to remove the Location column, you can just use this:

ddata$Location <- NULL

To get this:

#   Longitude   Latitude
# 1   33.9829  -118.3338
# 2   34.0454  -118.3157
# 3    33.942  -118.2717
# 4   33.9572  -118.2717

Hope it helps.
