Simple problem but I don't see the answer. I'm trying
to clean up some data
I have 120 columns in a data.frame. I have one value
in a column named "blaw" that I want to change. How do
I find the coordinates. I can find the row by doing a
subset on the data.frame but how do I find out here
"blaw " is in columns without manually counting them
or converting names(Df) to a list and reading down the
list.
Simple example
cat < c( 3,5,6,8,0)
dog < c(3,5,3,6, 0)
rat < c (5, 5, 4, 9, 0)
bat < c( 12, 42, 45, 32, 54)
Df < data.frame(cbind(cat, dog, rat, bat))
Df
subset(Df, bat >= 50)
results
cat dog rat bat
5 0 0 0 54
Thus I know that my target is in row 5 but how do I
figure out where 'bat' is?
All I want to do is be able to say
Df[5,4] < 100
Is there some way to have function(bat) return the
column number: some kind of a colnum() function? I
had thought that I had found somthing in
library(gdata) matchcols but no luck.

Why not do it this way?
Df$bat < replace(Df$bat, Df$bat >=50, 100)

it is the wellknown wicked which problem: if you had (grammatically
incorrectly)
thought "... which I want to change" then you might have been led
to type (in another window):
?which
and you would have seen the light. Maybe that() should be an alias
for which()?

I knew it was going to be blinding obvious! I even
read
?which somehow misunderstood arr.ind.

Thank you, I have never used grep. More reading :(

Maybe because it is too blinding simple? I'm still
thinking in SAS or Systat.
A great solution

One also has to understand which and I missed it. I
don't think that which is really that grammatically
incorrect anymore.

Is that any different, performancewise, than the following?
Df$bat[Df$bat >= 50] < 100

This works very nicely as has some other suggestions
on how to replace a value. Assuming that I have more
than one correction to make where Df >= 50, can I use
vectors in the Df[] to do this.
My attempt shows that I can use vectors but it appears
thatthere is something wrong with my logic
Eample
cat < c( 3,5,6,8,0)
dog < c(3,5,3,6, 0)
rat < c (5, 5, 4, 9, 51)
bat < c( 12, 42, 45, 32, 54)
Df < data.frame(cbind(cat, dog, rat, bat))
post < which(Df >= 50, arr.ind=T) # find values .=
50
post
correction < c(77, 88) # new correct values
row < post[ ,1] # vector for row number
col < post[ ,2] # vector for column number
Df[row,col] < correction
Df
result
cat dog rat bat
1 3 3 5 12
2 5 5 5 42
3 6 3 4 45
4 8 6 9 32
5 0 0 88 88
I am replacing both instances with 88 which is not
correct

You're being bitten by two issues here: One is that Df[row,col] does
not vectorize in parallel in the two indices: Df[1:2,1:2] has *four*
elements, not two. Another is that data frames are not matrices: you
can have different types of values in different columns, so you cannot
expect to pick an arbitrary set of elements and assign a vector into
it (well, it doesn't work, anyway).
This sort of stuff works much easier with matrices, where we also have
the wonderful feature of indexing with a matrix:

It took a moment to see it but it's rather obvious
now. I'm still fuzzy on the differences in behaviour
between a data frame and a matrix.
