To replicate:
install.packages('quantmod', repos='http://r-forge.r-project.org')

m <- getFinancials('MMM')
Warning message:
In readLines(tmp) :
incomplete final line found on '/tmp/Rtmpx3fWOf/file461821442a0b'
m
[1] 'MMM.f'
viewFin(m)
Error in viewFin(m) : ‘x’ must be of type ‘financials’

I've tried this in both windows and linux, versions from both the r-forge and cran.

As Garrett See said, this is expected behavior, therefore not a bug.

This warning message made me think something is just wrong with parsing of the answer, plus the variable was created which confused me further but it actually works after setting the auto.assign! Thanks a lot.

Any way to eliminate that warning? Maybe we should append empty line to the file before storing it?

This is expected behavior. getFinancials() is similar to getSymbols() in that it has an auto.assign argument that is TRUE by default. So, when you assign the results of your call to m, you are really just assigning the name of the object that was assigned in the .GlobalEnv. Then, you are calling viewFin() with m which is 'character', not 'financials'

Here are 2 solutions:

m <- getFinancials('MMM', auto.assign=FALSE)
viewFin(m)

getFinancials('MMM')
viewFin(MMM.f)
