Hi Ralf, thanks for sharing! I want to make predictive analysis in R, but I couldn’t understand exactly which variables should I include my model. I need to predict the availability of some charge units. How can I use longitude, latitude and street? Thanks in advance

hallo. thanks so much for this video. But I am having challenges with importing data from spss and dealing with the analysis as 99% of the data are categorical. Could you please provide additional support?

I have primarily been working with SPSS (and have a basic knowledge of statistics) but I have a question – when you run the “correlation” bw continuous variables is it a Pearson’s or Spearman? Your videos are outstanding by the way!

Hello Ralf, thanks a lot for your time to produce these excellent videos. I am trying to use “Tally” function but R is saying:
Warning in install.packages :
package ‘tally’ is not available (for R version 3.4.2) . is there an alternative function for Tally for R version 3.4.2? Many thanks

Hi, Thanks for this wonderful practical session! It was very useful!

I have a question related to selection of the specific variable. In your case it was hours>0. My R studio does not want to execute this command but when I did like “hours”>0, it worked. Can you help me? Thanks in advance.

Hello Ralf Becker, thanks for your video! However, I have some questions. I have a model, which has 10 factors, and I collected data with survey (seven-likert scale), every variable has three questions to measure. For example, Factor 1(Q1.1, Q1.2,Q1.3), Factor2(Q2.1,Q2.2,Q2.3), etc. So I can obtain data of every question, but not data of every factor. I don’t know how can I calculate number of every factor…Thank you very much!

Hey Ralf, great work thank you very much. For some reason some of the variables in this data frame are included as factors instead of numerical. For example the wage variables are indicated as factors – for that reason I cannot run the cor command for education and wage, as of course R tells me it needs numerical values. Have you any idea what might be the problem there? Thanks!

Thank you very much for your great works! But I tried to install mosaic but failed with this following comments. Could you let me know what I do now for mosaic?
————————————————————————————————————-
Installing package into ‘C:/Users/hw/Documents/R/win-library/3.2’
(as ‘lib’ is unspecified)
also installing the dependencies ‘rlang’, ‘ggformula’, ‘mosaicCore’

There is a binary version available but the source
version is later:
binary source needs_compilation
mosaic 0.14.4 1.1.0 FALSE

Package which is only available in source form, and
may need compilation of C/C++/Fortran: ‘rlang’
These will not be installed
installing the source packages ‘ggformula’, ‘mosaicCore’, ‘mosaic’

Ralf, you have done a great job for the R learners, especially for the beginners. Can you please tell me the shortcut way to replace/edit multiple similar parts in R script? Thanks!!

Zerxyo Sánchez says:

I downloaded the Mosaic package using Tools>Install Packages… and selecting/installing “mosaic” but when I run it, it tells me there is a problem with “dplyr”; did I do something wrong or this package has outdated? :s
