Ever since updating to the latest RStudio (Version 1.2.1335), some of my data frames don't have the handy blue circle that let's me easily check the column types.
This data frame for instance I think is fairly common looking:
> str(fl_MRL)
'data.frame': 6396 obs. of 6 variables:
$ Wavelength: Factor w/ 6396 levels "240/290","240/292",..: 1 2 3 4 5 6 7 8 9 10 ...
$ mean : num 0.0549 0.0556 0.057 0.0512 0.0562 ...
$ max : num 0.401 0.413 0.622 0.35 0.444 ...
$ min : num -0.034666 0.000638 -0.023195 -0.006206 -0.020597 ...
$ sd : num 0.0811 0.0755 0.1018 0.0728 0.0896 ...
$ MRL : num 0.298 0.282 0.362 0.27 0.325 ...
As I'm messing around, I think I can reproduce it when there's a factor and a numeric:
x <- data.frame(a = c("1","b"), b = 1:2)
that doesn't have the blue circle, but
x <- data.frame(a = c("1","b"))
does!
So yeah...can we get back the blue circle when there's a factor and numeric data frame?
