[R] Confused by dlnorm - densities do not match histogram

Good evening! I'm running into some surprising behavior with dlnorm() and trying to understand it. To set the stage, I'll plot the density and overlay a normal distribution. This works exactly as expected; the two graphs align quite closely: qplot(data=data.frame(x=rnorm(1e5,4,2)),x=x,stat='dens

I need to learn how to apply the methods in robCompositions and have read the package docs. Two of my six data sets of proportions contain missing values (not collected or not present); one set has a single missing value, the other has 3 missing values. So my first task is to learn how to proper

[R] Error in quantile.default(resids) : missing values and NaN's not allowed if 'na.rm' is FALSE

About a year ago I ran some analyses using lmer. The general syntax was: mlm <- lmer(var1 ~ (1|dyad) + var2 + var3*var4*var5, na.action=na.exclude); summary(mlm) The model ran fine and I saved the output. I've recently turned back to those analyses, however, the model no longer runs. I get the fo

[R] error in rownames

Dear fellow R users, I am trying to run the random forest and Yaimpute packages in R to impute a grid to project in a gis. However, after running the imputation I keep getting an error in the rownames. This sounds simple enough, but I cannot figure out what these rownames are reffering to. Any ide

Unfortunately in this specific case the owner/maintainer is a complete idiot and a major jerk... he is.. well.. me in this case. But, this is something I have also been wanting to figure out for some time as it is often the case when a quick and simple regex based "patch" to a function can be usefu

If you really want to continue to use the function in the supported package, then you could try asking the maintainer of the package to make the problematic URL an argument to the function. I thnk that changing the function on the fly, no matter how you do it, is likely to cause problems when the

That seems right to me. You might want to look into a persistent connection as in Example 10 at https://code.google.com/p/sqldf/#Example_10._Persistent_Connections This will save reloading the DB for every query. You might even want to create a permanent DB as in Example 9. This is one of my
