This is really helpful. Thank you a lot.

I am really confuse about how to represent it. Thank you again.

Can you share few rows of data, so that i can understand requirement and think of solution.

[@md.mahamudulhasanmredul9433]

Very nice vedio, and informative. Do you know how to add ANOVA or significance value in a group boxplot!!

[@muralikrishna59]

Here Rajendra Choure used Readily available SD values. In fact, we can also calculate, Mean, SD or SE from variables observations.

[@DevResearch]

Yes, those are actually calculated using summarise function of Dplyr. This function applies any other function to all categories in the variable.

[@homaanrandm9441]

I have a dataset and I need to use descriptive statistic or logistic regression can you help. if yes let me know then we can talk about the rest.

[@DevResearch]

If data is clean it's easy to apply any function. Descriptive stat is different for different purposes. If you need that for paper or thesis or can become using gt table. Lm is too straightforward if you you know response and predictor variables.

[@homaanrandm9441]

@@DevResearch I really appreciate your response. Actually I have to do logistic regression

[@khatrikumar9134]

Can we cut down the high value of bar plot to look good with low value in ggplot2 as in origin

[@DevResearch]

Sincere apologies for replying late. This shall not be done to bar plot as the minor differences will be exaggerated. But still if you need to do this then a great lot of coding is required to trick geom bar to limit the axis.

[@companywithout]

Hey, thanks a mil for this. I'm having some trouble when doing this on my own dataframe.. when I calculate mean and sd, it just returns NAs and . I can get means when I use summarise_at(c("length"), mean, na.rm = TRUE) but no luck with creating SDs or SEs columns. Any advice?

Need to see the data. It happened with me some times, but I forgot the context. Can figure out with your dat.

[@DevResearch]

Great suggestion!

[@kyriakib6266]

Thank you for this great video! Can you tell me what is the difference between line 66 and 70 of the code? I see they both return the same result,?

[@DevResearch]

line 66 is df_sumzd=group_by(df_long,Species) here just grouping is done. This i used to demonstrate the grouping only. Result gets saved as object df_sumzd On line 70 df_sumzd=group_by(df_long,Species,Mes_type) %>% summarise(mean=mean(length),sd=sd(length)) i Hve added the code for summarizing , and again the result gets saved as df_sumz. here the output of line 66 gets replaced by output of line 70. And now df_sumz will show you the output of line 70 only and not of line 66. If you clean up the environment and run the code form line 26 again you will get grouping results for line 66, which will get replaced by output of line 70, when you run the line 70. group_by() function groups the numeric output by the combination of categorical grouping variables.

[@kratikaarora1879]

Hello sir, Can you tell if we have very big dataset but on barplot we want to show top 5, How will do that ?

[@DevResearch]

you need to order the data , you can use arrange() fucntion of dplyr, then subset the data to filter out top five observations or groups as you require and then go for barplot.

I have a problem converting an Excel sheet in a *.csv file. I've searched all day for solutions, but nothing seems to work. After I select the sheet and save it as "CSV(Comma delimited)", pressing OK and Yes as Excel tells me there could be some problems, the file opens in format .csv without putting all the date in one column separated by commas... it just remains the same and obviously I get an error when I try to open it with R. Is there someone who had the same problem? Did you find the solution? I even uninstalled and reinstalled Microsoft Office 2016 or cancelled the last two columns because they contain commas. Nothing works... I would really appreciate if you could help me. Thank you!

[@DevResearch]

If possible send me the Excel file and the r code which you are using by mail to [e-mail]. After converting excel to csv don't open the file in excel. right click the file and use open with option. Open the file with notepad. You will see comma separated values. I save he file in the same folder where i store my R file. I set that folder as the working directory, and use read.csv("filename.csv") to import the csv file in R . I store it in a data frame.
