For example, based on a certain condition, I may want to exit my code early: # Are there the same number of assets in "prices" and "positions"? if (nAssetPositions != nAssetPrices) { cat("Different number of assets! \n\n") <exit function> } I have searched, but not

I am trying to change the number format shown on the y-axis from scientific 5e05, to 500,000 etc. Does anyone know how to do this? Is there something I can add as an argument to barplot, or would it be through par? barplot(data$Value, names.arg = as.vector(data$Field), main=strTitle) [[alternative HTML version deleted]]

Hi all, I would like to generate nicely formatted reports on a daily basis. The reports would be a combination of charts and tables, generated in an environment such as R. Ideally, this would be an automated process. Does anyone know if this is feasible, and how I could achieve well formatted reports? One idea would be to have R scripts process the data/generate the charts and then use

I have the following data frames, avGain and retGain. They have the same dimensions. The following line of code replaces row j of avGain as desired: avGain[j, ] <- mean( retGain[jStart:j, ] ) However, the following line does not work: avGain[j, ] <- ( avGain[j-1, ] * ( DAYS - 1 ) + retGain[j, ] ) / DAYS If I do the following, and test to see if a or b are data frames.

Hi there, I've spent a while searching for ways of outputting table data from R in presentable formats, such as colored backgrounds for column headings, bold fonts etc. It appears that this is not possible, but I would be interested to learn if in fact there was a way of achieving this. Many thanks! [[alternative HTML version deleted]]

Hi, I've written some code that fetches data from an Access Database (2003), processes the data, then saves the modified data back into a table in the Access database. It works if I only pass through the code once, but if I put a loop around the code so that I fetch data from a different source table, and then save it again to a different destination table, the code crashes. It is
