Good day house. Please I need the assistance of anyone good in the use of R for data analysis.
I have six groups (1 - 6) which are Factors i.e Categorical variables and each of these 6 groups have 3 subsets (A , B, and C) which are factors also i.e Categorical variables. So my groups are like 1A, 1B, 1C, 2A, 2B, 2C, .......6A, 6B, 6C. Each of these groups has 5 samples.
I need example of R code that will calculate say MEAN +/- SD for each of the groups and output a Bar Chart such that 1A, 1B and 1C will be side by side but colour differentiated. It means all the As will have same colour, Bs same colours and Cs same colours.
Thanks.
