Hi R-helpers,
I intend to record the errors in my R code while calling functions in a
dataframe (ERR_LOG, say). I want to use 'try' to identify errors while
calling a function,if any.The dataframe(ERR_LOG) will have the following
columns :
Time : The time at which the function was called
I have the datafram like fxmale
head(fxmale)
x y D.fx D.ncD.sum1 445350
2463450 1.046935e-06 0.0002627856 0.00026383262 445350 2463950
1.314861e-06 0.0002618268 0.00026314163 445350 2464450 1.435987e-06

Hello,
Your data.frame only has 2 columns, x and y. The rest are attributes of
the column y. To access those attributes you can use something like
attr(fxmale, covariates) # This is the one you want
attr(fxmale, meanSD)
attr(fxmale, boundingbox)
and save them in other csv files (most
In R:
factor(30, levels=1:30)
[1] NA
30 Levels: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 ...
30
The NA above is undesirable in my view, because 30 is in 1:30.
I have just got bitten by it.
I have figured out why it happens. The results of
I would say having 30 levels is a bad idea... You should be re-thinking
your analysis.
If you are still convinced that this is necessary, then do it right:
factor(30L, levels=1:30)

You could also use Rvmmin
that has bounds, or nmkb from dfoptim (though you
cannot start on bounds).
One 'negative' for dfoptim is that is doesn't automatically generate the
Hessian (as far as I can tell). Rather nice to be able to do so
You can work around this issue by matching the types of the the 'x'
and 'levels' arguments to factor():
factor(30, as.numeric(29:31)) # both are floating
point ('numeric')
[1] 3e+05
Levels: 29 3e+05 31
factor(as.integer(30), 29:31) # both are integer
[1]

Thanks Henrick. Seems it fits my needs. One my question is the argument,
length.out=0.10*n, is it randomly taking out 10% ? I found it basically
takes every 10th row if I put length.out=0.1*n, and every 100th row if

Dear all,
I have a data.frame xy which I am plotting like in the code below (provided
is a small data sample with dummy data that should work).
Is there a way how I could convert my xx and yy in the xy plot to a points
