Workplace doesn’t remain work place when you have good friends around you

Topbullets.comI remember one video from my childhood where kids run for school and the lyrics was like we leave our houses early in the morning to meet friends in school.

You may get satisfied with your work, appraisal or salary or a warm handshake from your manager congratulating you in front of everyone but do we really want to see them tomorrow again?

Exporting multiple graphs in same plot to PDF in R – TopBullets.com

Topbullets.comAs being a data scientist, plotting data is one of the first things we generally do. Without studying the behavior of the data we can’t or rather should not move ahead. There can be a lot of analysis which we can perform by plotting the graphs for example univariate, bivariate and residual plots. In my earlier blog, I wrote about how to plot two graphs in the same plot using par () function in R which is very useful when we do bivariate analysis and want to see the behavior of 2 variables across different time duration. Today I will write how to export the plots in PDF and in a tabular format. Generally exporting plots in any format (JPG, PDF) is an easier task but when you have say 50 graphs, you won’t want 50 pages, rather you will want 4 graphs in one page which will be very easier to read or interpret.

How to download data from Weather Underground – TopBullets.com

Topbullets.comWeather is an important factor for fast moving consumer goods product. It is a very interesting case study to read upon. Milk which is the major component for ice cream is heavily produced during winter as cows produce more in this season but consumed more in summer. So dairy products manufacturers have to adjust their storage of raw material and production of final products in such a way which can minimize the operational cost. Forecasting of FMCG products is also very important for manufacturer and temperature play again an important role to understand the demand. To understand the relation between temperature and demand we need historical data. So today I am going to write an R code and some manual trick to download the temperature data for different cities.

How to plot two graphs in the same plot in R and R Shiny

Topbullets.comWe as data analyst always have to do basic EDA or data manipulating before sorting the variable for developing any model. One of the first steps that we follow in EDA is bi-variate analysis. I will not go into details how or why we do bi-variate analysis, as you must know already and just want to learn how to plot 2 graphs in the same plot area in R. So let’s get started. I simply wrote an R code with comments to understand each step. Please check out the code below and comment if any step is not clear. Good luck. Continue reading
