I have 20 columns of data, and in column 5 I have a value of 17600 but I dont know which row this value is in (i have over 300,000 rows). I'm trying to do 2 things: 1) I want to find out which row in column 5 has this number in it. 2) Then I want to print out that row with all the column headers so i can look at the other parameters in the row that are associated with this value. How do i

Please help me persuade IT to install R on my computer! All suggestions welcome. Our IT department run scared when you mention software that they have no working experience of. I need to know the pros and cons of having R on corporate desktops. Please no funny stuff, this is quite a serious issue for us. Pros and cons would be good. Thanks. -- View this message in context:

I want to go through a column in data called date_abandoned....data["date_abandoned"]....and remove all the rows that have numbers greater than 1,010,000. The dates are in the format 20091114 so i'm just going to treat them as numbers for clean up purposes. I know that i use subset but not sure how to proceed from there. -- View this message in context:

What ways are there to plot categorical vs numerical data in R. I have two columns: one with categorical data in 5 categories a,b,c,d,e, and a numerical column with integers between 1 and 100. I have used a boxplot with a,b,c,d,e on the x-axis and an increasing numerical scale on the y-axis. This look fine but im looking for other ways to present the data. What other ways can i do this??? --

I need to find out the difference between the way R calculates weighted regression and standard regression.
