Import ASCII file into R

How can I Import this? I wasn't succesfull with read.table, but I would like to have it in a data.frame Format.

<Security Name> <Ticker> <Per> <Date> <Close>
Test Description,Test,D,19700101,1.0000
Test Description,Test,D,19700102,1.5

If you really want to force the column names into R, you could use something like that:

# Data
dat <- read.csv("/path/to/data.dat", header = FALSE, skip = 1)
dat
                V1   V2 V3       V4  V5
1 Test Description Test  D 19700101 1.0
2 Test Description Test  D 19700102 1.5


# Column names
dat.names <- readLines("/path/to/data.dat", n = 1)
names(dat) <- unlist(strsplit(gsub(">", " ", gsub("<", "", dat.names)), "  "))
dat
     Security Name Ticker Per     Date Close 
1 Test Description   Test   D 19700101    1.0
2 Test Description   Test   D 19700102    1.5

Although I think there might be better solutions, e.g. manually adding the header...

You can easily read this data using read.csv. Since your column names are not comma separated then you will need to use the header=FALSE argument and then add the names once the data is in R or oyu can manually edit the data before reading it by omitting the <> characters and adding a comma between each column name.
