?Hey All, I have a txt data file that looks like this:
?[{?ID???A???Name":"Tom",
"Age":"18"},{?ID???B???Name":"Jim",
"Age":"19"}]
?How can I read this into R as a data frame? I have used readLines to read
all the lines but dont know how to deal with column names and inputs.
Thanks for your help!?

Please change to plain text. In many cases HTML displays poorly due to the list trying to change it for you to plain text. And, in that case, you'll likely be ignored. ? -- Yoda of Borg, we are.

This is (almost) json data (but see NOTE below); there are several packages that
deal with json, jsonlite for example.
R > data <- '[{"ID":"A",
"Name":"Tom",
"Age":"18"},{"ID":"B",
"Name":"Jim", "Age":"19"}]'
R > install.packages("jsonlite")
R > library(jsonlite)
R > myDf <- fromJSON(data, simplifyDataFrame=TRUE)
R > str(myDf)
'data.frame': 2 obs. of 3 variables:
$ ID : chr "A" "B"
$ Name: chr "Tom" "Jim"
$ Age : chr "18" "19"
NOTE: some of the quotation marks in your example are messed up, and some of
your commas and colons seem to use an Asian font - i.e. they are UTF, not ASCII.
You will need to clean up all the non ASCII characters that are syntactically
important, otherwise things break.
Cheers,
Boris
