R Programming expert -- 2

Hi there, This is J.
I need someone who is an expert in R programming. (complete details will be shared with selected candidates only)
we are going to construct a predictive model for
horse races. The dataset (races.csv and runs.csv) contains the
information about 1000 horse races in Hong Kong during the years
1997-1998 (originally from <https://www.kaggle.com/gdaley/hkracing>).
Races.csv contains information about each race (such as distance, venue,
track conditions, etc.), while runs.csv contains information about each
horse participating in each race (such as finish time in the race).
Detailed description of all columns in these files is available in the
file horse_racing_data_info.txt.**

**Our goal is to model the mean speed of each horse during the races
based on covariates available before the race begins.**

**We are going to use INLA to fit several different regression models to
this dataset. First, we load ILNA and the datasets and display the first
few rows.**
