Hello and Thanks in advance for your suggestions. As a new member, I do not know exactly if such problem has ever been discussed in this forum. I need a small help using FactoMineR and RcmdrPlugin.FactoMineR package to calculate weights for the individual observational units. My data looks like: You can treat the data spaced instead of tabbed. (I_1_3)(I_1_4)(Weight_I_1)(I_2_1)(I_2_2)(I_2_3)(I_2_4)(I_2_5)(I_2_6)(I_2_7)(I_2_8)(Weight_I_2)20-22223122-20-22223122-30-22213342-30-22213342-30-22223322-24-02112222-24-02112222-23-20013143-23-20013143-34-02013144-35-22213144-35-20013111-34-22213322-30-22111322- up to 55 observations and more variables, where the header are names of 12 variables in the data and each value is for corresponding variable while "-" is the required (to find) weights. I think I will get the idea if someone help with piece of code for one variable of the example data above above. I need to fill the columns of weights (now - but actually new variables) for the variables. Please note that I (may) need to use Multiple Correspondence Analysis (MCA), MFA, PCA etc but I dont know exactly. I would highly appreciate a code if possible from using the two packages above. I am sorry if this is not that clear. I can guess I will be pardoned being new old guy here. Thanks, Best Anees [[alternative HTML version deleted]]
