Your data frame fam contains factors. Turn it into character strings using
fam$Family = as.character(fam$Family)
and try again. It may be helpful if you read up on R's factors, see ?factor.

This is a simple problem, but a mystery to me.
I'm trying to grab $Family "Scelionidae" from one dataframe and put it into
another dataframe occupied with NA in $Family. The result is a "158" ends
up there instead of Scelionidae.
Simply put fam$Family[1] <- least$Family[1]

Dear useRs,
I'm pleased to announce the v1.0.0 major release of the "elo" package on CRAN

This package implements a flexible framework for calculating Elo ratings of any

1) What is easy for one person may be very hard for another, so your question
is really unanswerable. You do need to know C and Fortran to get through the
source code. Get started soon reading the R Internals document if it sounds

Dear R Users,
We are pleased to announce the first release of CVXR which implements
Disciplined Convex Programming (DCP) in R on CRAN. Like CVXPY in Python,
CVXR provides a domain specific language for formulating
convexoptimization problems in a natural way following mathematical
convention a

Thank you, that helps a lot. If I'm understanding correctly, if I’m wanting
to use actual returns from backtests rather than simulated returns, I would
need to make sure my risk-adjusted return measure, sharpe ratio in this
case, matches up in scale with my returns (i.e. daily returns wit
