Dear all: This is a quick post to let you know I developed two #rspatial packages (sf based), both available on CRAN: giscoR downloads geospatial data from the GISCO (Geographic Information System of the Commission) Eurostat database. It is quite convenient to run the script from the Terminal command line with "Rscript scriptname.R" However, some datasets will cause errors. IFERROR returns a value you specify if a formula evaluates to an error; otherwise, it returns the result of the formula. > results from ee and not from ff. Combining the example by @Robert and code from the answer featured here: How to get a reversed, log10 scale in ggplot2? where myfun(x)==0): uniroot(myfun,interval=c(0,30000)) $root [1] 28356.39 $f.root [1] 1.482476e-08 $iter [1] 4 $init.it [1] NA $estim.prec [1] 6.103517e-05 ... if (length(z) %% 2) { z[-c(1, ceiling(length(z)/2), length(z))] } else z[-c(1, c(1,0) + floor(length(z)/2), length(z))] ... R prefers to use i rather than j. Aslo note that complex is different than as.complex and the latter is used for conversion. I get multiple such errors on the same 1 MB file and it may take 10-20 min to proceed to the next file, which may or may not give similar errors. It's easier to think of it in terms of the two exposures that aren't used, rather than the five that are. The function author signals conditions with functions like stop() (for errors), warning() (for warnings), and message() (for messages), then the function user can handle them with … > This should get you headed in the right direction, but be sure to check out the examples pointed out by @Jaap in the comments. Finally, we looked at the errors caused by the downloaded packages and how we can resolve those. In a nutshell, the function simply says that if the ‘value’ argument is an error, then return the ‘value_if_error’. Joris You can see in vector vec - all ok values except where there's an error. expFit is defined as . Errors will be truncated to getOption("warning.length") characters, default 1000. If the specified file is "", then input is taken from the keyboard (or whatever stdin() reads if input is redirected or R is embedded). I often intervene by clicking Stop and then, after R-Studio finally responds, tell it to skip the file. > Paul When we run the code above, the output is the number 5.

In such cases, I want to skip the iterations and want to move to the next iteration ignoring all the subsequent computations. search. The test script at the end of this post demonstrates how messages and errors can be generated within a function and then trapped and processed by a calling function, potentially generating new errors that could be passed upstream.

HTH, Thierry ----- ---- ir. Function authors can also communicate with their users with print() or cat(), but I think that’s a bad idea because it’s hard to capture and selectively ignore this sort of output. If the ‘value’ argument is not an error, the function will return that value. For the example, I fit a linear mixed effects model using lmer (just because I happen to be working with mixed models, and they throw back convergence errors more often than GLMs), then used the update function to challenge it with random draws from my dataframe.
