[R] How to convert category (or range/group) into continuous ?

[Marna Wagley]

Hi R users,
I first categorized the continuous data into groups (ranges or category)
but now I would like to change the category into a continuous data and
plot it. For example I have attached the data in which you can see two
columns named "group" and "value". The group column contains a range
(group, for example ), I am wondering how I can change the category data
(for example: "0,0.01]" )into continuous data with a 0.1 interval.
Thank you for your suggestions.

daT<-structure(list(group = c("(0,0.01]", "(0.01,0.025]", "(0.025,0.05]",
"(0.05,0.075]", "(0.075,0.1]", "(0.1,0.2]", "(0.2,0.3]", "(0.3,0.4]",
"(0.4,0.5]", "(0.5,0.6]", "(0.6,0.7]", "(0.7,0.8]", "(0.8,0.9]",
"(0.9,1]", "(1,1.1]", "(1.1,1.5]", "(1.5,2]", "(2,2.5]"), VALUE = c(1,
1, 1, 1, 1, 1, 0.944444444, 0.916666667, 0.888888889, 0.857777778,
0.826666667, 0.66, 0.439090909, 0.328636364, 0.273409091, 0.245795455,
 0.218181818, 0.084848485)), class = "data.frame", row.names = c(NA,
-18L))
thanks,
MW
